Koongso Girls Matilda Costume Review: a decent World Book Day outfit that keeps things simple

I got this Koongso girls "book character" costume in size 130 for a World Book Day event at school, basically to do a Matilda-style outfit without having to hunt bits from different shops. It’s the full set: grey jacket, white shirt, black skirt and the red/white checked tie. On paper it ticks all the boxes for a quick Roald Dahl day solution, so I wanted to see if it actually holds up in real life with a kid wearing it all day.

The context: my daughter is average height for her age, usually wears 7–8 years clothes, and standard supermarket school uniforms fit her fine. I was mainly looking for three things: does it look enough like the character so teachers and kids get it, is it comfortable enough for a full school day, and is it going to fall apart after one wear or survive a couple of events and maybe some dress-up play at home.

Out of the bag, my first impression was pretty neutral: it looks like a basic British school uniform set with a printed badge on the jacket. Nothing fancy, but not costume-shop terrible either. The colours are what you expect – grey jacket, plain white shirt, black skirt – and the tie adds the book-character touch. You can tell straightaway it’s polyester-heavy, but that’s normal for this type of outfit at this price.

Overall, after seeing it on her for a school event and then again for some dress-up at home, I’d say it does the job as a themed costume. It’s not high-end clothing, and I wouldn’t treat it like a proper school uniform for daily wear, but for World Book Day, parties and Halloween, it’s pretty solid. There are a few small annoyances and some clear cost-cutting in the details, but nothing that made me regret buying it.

On value, I’d call this good but not mind-blowing. You’re mainly paying for the fact that it’s a complete outfit that looks like a known character without needing extra effort. If you had to buy a grey jacket, white shirt, black skirt and tie separately, you’d probably spend more than this, even in budget shops, and they might not match the “book character” vibe as neatly. So for parents who just want to tick the World Book Day box without running around town, it’s worth it.

Compared to other kids’ fancy dress costumes we’ve had (princess dresses, superhero outfits, etc.), the quality is roughly on par or slightly better, but this one has the advantage of being reusable as generic school-style dress-up. My daughter has already used the skirt and shirt separately for playing "school" at home, so you get a bit more mileage than with a single-purpose costume. The fact that it’s machine washable and doesn’t fall apart immediately also helps justify the price.

On the downside, it’s still clearly not proper uniform quality. If you were thinking “I’ll buy this and she can wear it as real school clothes too”, I’d say that’s pushing it. For daily wear, you’d be better off buying actual school uniform pieces from a supermarket or clothing brand. This set sits in that middle ground: nicer and more complete than throwaway costumes, but not tough enough to replace everyday clothes.

Given the current prices of kids’ costumes and the fact this has a 4.2/5 rating on Amazon with a handful of reviews, I think the value is fair. You’re not getting a bargain of the century, but you’re also not overpaying for something flimsy. If you need a quick, recognisable Matilda-style outfit that you can reuse a few times, the price makes sense. If you’re on a very tight budget and already own a white shirt and black skirt, you might be better off just buying a cheap tie and improvising the rest.

The main design idea is simple: iconic British school uniform style with a couple of details to hint at Matilda. You’ve got a slim-fit grey jacket with a lapel collar and printed badge, a plain white short-sleeve shirt, a black skirt, and the checked tie. It’s basically what you’d expect a generic movie school outfit to look like. From a few metres away, it looks the part in photos and on stage, which is what most people will use it for.

The jacket is single-breasted with buttons down the front. It’s not heavily structured, no lining, and the lapels are quite simple. The printed badge is what makes it feel more "character" than just school uniform. Up close, you can see it’s printed rather than embroidered, but kids don’t care and it shows up well in photos. The skirt is straight and simple, more like a basic A-line than a pleated school skirt. If you’re used to supermarket pleated skirts, this one feels a bit flatter and lighter.

The shirt is a straightforward short-sleeve white button-up with a lapel-style collar. No fancy darts or tailoring, just a basic cut. The tie is the fun bit: red and white checked/striped pattern that gives the whole outfit a bit of colour. It’s not pre-tied; you actually have to knot it yourself, which is fine if you know how to tie a tie, less ideal if you were hoping for a clip-on. For a costume, I would have preferred a simple elastic or clip tie so kids could manage it alone.

On my daughter, who’s quite slim, the slim fit description is accurate: it sits close to the body without being tight. If your child is on the broader side or you like room for layers underneath, I’d seriously consider sizing up. The overall look is neat and recognisable, especially once you add black shoes and ankle socks like the listing suggests. It’s not stylish in a fashion sense, but as a school-themed costume, the design is straightforward and does what it should.

Comfort was my biggest concern because my daughter wore this for a full World Book Day at school, not just for a one-hour party. Overall, she said it was “comfy, not itchy”, which is basically the main thing I wanted to hear. The fabric is smooth, not rough, and there are no weird scratchy labels or stiff seams rubbing against the skin. She wore a vest and normal underwear underneath, plus ankle socks and black shoes, and didn’t ask to take anything off during the day.

The short sleeves on the shirt are a good call for classroom wear. In a warm classroom, long sleeves under a jacket would have been too hot. She ended up taking the jacket off for part of the day and just kept the shirt, tie, and skirt, and that combo worked fine. The jacket itself is light, so when she had it on, she didn’t overheat. If you’re sending a child out in colder weather, you’ll still need a proper coat on top for the journey, because this “coat” is basically just a blazer-style top, not outerwear.

Fit-wise, the size 130 on my average-height kid sat well. The slim fit means it follows the body but doesn’t squeeze. She could move her arms freely, sit on the floor for story time, and run around at break without complaining. The waistband on the skirt is not brutally tight but snug enough that it stayed up all day without needing adjustment. She went to the toilet by herself with no drama – the closure is simple enough for kids to handle, and there are no annoying zips hidden at the back.

The only small comfort gripe was the tie. Because it’s not a clip-on, I tied it for her in the morning. By lunchtime it had loosened and she asked her teacher to help tighten it, which is a bit of a pain. For older kids that can tie a tie themselves, it’s fine, but for younger ones it adds a small hassle. Apart from that, no rubbing, no red marks, and she was happy to put it on again later at home, which is usually the best sign that the comfort is acceptable.

Material-wise, this is very clearly a polyester/cotton blend leaning heavily toward polyester. The label and listing say polyester cotton blend, and that matches how it feels in hand: slightly smooth and synthetic, but not plastic-bag horrible. I’d call it medium weight – not see-through like some cheap costumes, but also not thick like proper schoolwear from Marks & Spencer or similar. For a costume, it’s on the better side of average.

The jacket fabric has a bit of structure but no lining, so it behaves more like a heavier shirt or cardigan. It’s fine for indoor wear and mild weather, but I wouldn’t rely on it as an actual jacket in cold conditions. The skirt is light and has a bit of movement, and my kid liked that it wasn’t stiff or scratchy. The shirt is the thinnest part of the set: breathable enough, but you can slightly see darker underwear through it if you look closely, so I put a plain vest underneath just to be safe for school.

The tie is pure costume fabric – thin polyester with a printed pattern. It does the job visually, but it creases easily, and out of the bag it needed a quick iron on low heat. The good thing is the whole set is easy to wash: I put everything except the tie into the machine on a gentle cycle, 30°C, inside out. No shrinking, no colour bleeding, and the grey stayed grey. I line-dried as the care label says and then gave the shirt and tie a light iron. The polyester content means it dries quickly and doesn’t wrinkle too badly.

In terms of safety and comfort, nothing smelled strongly of chemicals out of the bag, which is something I always check with imported costumes. There was a slight “new clothes” smell but it disappeared after one wash. Seams are reasonably finished; I didn’t see loose threads everywhere. You can tell it’s not premium fabric, but for the price point and the fact this is a dress-up costume, the materials are acceptable and slightly better than some Halloween outfits we’ve tried from random brands.

On durability, I’d say this sits in the "pretty solid for a costume, average for clothing" category. After a couple of wears and washes, I checked the typical weak points: seams at the armpits, waistband, and buttonholes. Nothing had ripped or stretched out. The stitching is not luxury-level, but it’s straight and reasonably tight. There were a few tiny loose threads when it arrived, which I snipped off, but nothing that affected the structure.

The skirt seems to be the toughest piece. The waistband has enough give without feeling like it’s going to lose elasticity quickly. My daughter did the usual kid stuff – running, sitting cross-legged, bending down – and the skirt didn’t sag or twist. The jacket, being unlined, is the bit I can see wearing out first if you use it a lot. The fabric will probably pill a bit under the arms or at the cuffs over time, like most polyester-blend jackets do. After two washes, though, it still looked presentable.

The shirt is the weakest link in terms of long-term durability. It’s thinner and shows creases more. For a costume, that’s fine, but if you were thinking of using it as a weekly school shirt, I don’t think it would last as long as a regular supermarket one. Buttons are sewn on okay, but I’d keep an eye on them if your kid is rough with clothes. The tie is clearly costume-grade and might fray a bit at the ends if you’re not careful, so I’d store it flat or rolled, not scrunched in a drawer.

Overall, I’m confident it will last through several themed days, parties, and home dress-up sessions. I wouldn’t expect it to look brand new after a year, but for occasional use it’s more than good enough. If you’ve ever bought those ultra-cheap costumes that basically fall apart after one wear, this is a step up. Just don’t treat it like a hard-wearing uniform and you’ll be fine.

In practice, the outfit did what I needed it to do: survive a busy school day, look like the character, and not fall apart. After one full day at school plus a couple of hours of dress-up play at home, all buttons were still attached, seams were intact, and the colours hadn’t faded. The skirt didn’t ride up or twist weirdly, and the jacket kept its shape reasonably well. When she came back, the set was a bit creased (normal for kids), but nothing out of the ordinary.

We then washed it on a gentle machine cycle, line-dried it, and used it again for a friend’s birthday party with a costume theme. The second wear looked pretty much the same as the first. The printed badge on the jacket didn’t crack or peel, which I half-expected from cheaper prints. I wouldn’t put it in a hot dryer though – the care label says no, and I think the print might suffer. As long as you stick to the instructions, it behaves like a regular polyester school outfit.

Compared to supermarket school uniforms we own, the performance is clearly lower if you plan daily wear. The fabric is lighter and will probably bobble sooner if you wash it every week. But compared to other kids’ fancy dress costumes we’ve tried (especially cheap Halloween ones), this one is more robust. It’s the kind of thing I’d expect to use several times over a year: World Book Day, Halloween, maybe a school play, and then keep in the dress-up box for random play.

One thing to flag: it’s described as suitable for “daily wear”. Personally, I wouldn’t use this as a real school uniform long-term. It’s fine for occasional use, but for everyday school clothes, I’d go with purpose-made uniforms that handle constant washing and playground abuse better. As a costume, though, the performance is solid: it looks right, it survives normal kid behaviour, and it’s easy enough to clean and reuse without stress.

The main factual point here: you really do get a full outfit ready to wear, you don’t need to add much apart from shoes and maybe a hair accessory. In the package I got: 1 grey coat, 1 white short-sleeve shirt, 1 black skirt, and 1 red-and-white checked tie. Everything came folded in a simple plastic bag, no fancy branding or extra packaging. It’s very “Amazon seller from China” style: functional, not pretty. Nothing was damaged or stained, which is what matters to me.

Each piece is clearly costume-grade, not proper school uniform quality, but it’s more complete than some sets where they only give you the dress with a fake jacket printed on. Here, it’s four separate pieces, which is useful because you can mix and match. For example, the white shirt is totally fine to wear with other skirts or trousers, and the black skirt could easily be used with a normal school shirt if you’re not too picky about fabric.

The listing talks a lot about Roald Dahl, Matilda, British school style, etc. In practice, the badge printed on the chest of the jacket and the striped tie are what make it look like a book character rather than generic uniform. There’s no official logo or anything, but for kids and teachers it’s obvious what it’s meant to be. My daughter went into class and her teacher immediately said “Oh, Matilda!” so from that point of view, it works.

One thing to be aware of: the product photos make it look slightly sharper and more structured than it is in real life. The jacket especially looks more tailored online. On the body, it’s a bit softer and more like a light cardigan with buttons than a proper blazer. Not a deal breaker, but if you’re expecting a stiff, lined blazer, that’s not what this is. Still, for a mid-priced costume, the overall presentation is decent and you get everything you need in one go.
