Koongso Girls Matilda Costume Review: a decent World Book Day outfit that does the job without costing a fortune

I got this Koongso girls book character costume (the Matilda-style school uniform in size 120) for my daughter for World Book Day at school. We didn’t want to spend a fortune on something she’d probably wear a few times, but I also didn’t want one of those paper-thin, scratchy outfits that fall apart before lunchtime. So this hit that middle ground: affordable, but hopefully not total rubbish.

We used it mainly for a Roald Dahl / Matilda dress-up day and then again for a birthday party with a book theme. So it’s had two proper outings plus a few try-on sessions at home. That’s enough to see how it holds up to real kid behaviour: running, sitting on the floor, eating cake, and the usual chaos.

The set includes four pieces: grey jacket, white shirt, black skirt and a red-and-white striped tie. No socks, no shoes, so you need to sort those yourself. My daughter wore it with plain black school shoes and white ankle socks and it looked close enough to the character that teachers and other parents knew straight away who she was meant to be.

Overall, my first impression was: it looks the part from a distance and for photos, but once you actually touch the fabric and look at the stitching, you can tell it’s a costume, not a real school uniform. That’s not necessarily a bad thing at this price, but you need to know what you’re buying: a decent fancy-dress outfit, not everyday schoolwear.

On the value side, I’d say this costume is good but not mind-blowing. You’re paying for a full four-piece set that comes ready to go: jacket, shirt, skirt, tie. If you tried to put together something similar from separate bits — buying a grey blazer, white shirt, black skirt and tie individually — you’d almost certainly spend more, even going budget. So for parents who just want a quick, complete Matilda-style outfit without hunting around shops, the price makes sense.

Compared to the really cheap supermarket costumes I’ve bought in the past for things like Halloween, this feels a notch up. The fabric isn’t luxury, but it’s thicker than those flimsy outfits that almost tear when you look at them. On the other hand, compared to a proper school uniform brand, it’s clearly lower quality and less durable, so I wouldn’t say it’s a bargain in that sense; it’s a costume-priced item that behaves like a costume.

The real question is how often you’ll use it. If it’s just for one World Book Day and that’s it, you might feel like you’ve paid a bit much for a single wear, like with most fancy-dress stuff. But if you know your kid will also wear it for Halloween, book week, maybe a school play or just imaginative play at home, then the cost per use drops quickly and it starts to feel like decent value for money.

For me, because my daughter has already used it twice and is talking about wearing it again for Halloween, I’m happy with what I paid. It’s not some hidden gem, but it does the job, looks right in photos, and hasn’t fallen apart. If you’re on a very tight budget, you could probably DIY something similar from second-hand clothes. If you want something simple that arrives ready-made and looks clearly like a book character, this Koongso set is a pretty solid compromise between price, effort and quality.

The overall design is clearly based on that British school uniform style you see in the Matilda movie and musical: grey blazer-style jacket, white shirt, dark skirt and a tie. If you’re buying it for Roald Dahl / World Book Day, people will get the reference straight away even though it doesn’t use any official logos. My daughter got called “Matilda” by half her class all day, so design-wise, it does what it’s supposed to do.

The jacket has a single-breasted look with a lapel collar and a printed badge on the chest. The badge is just ink on fabric, not a patch, so don’t expect anything fancy. The cut is slightly slim so it looks more like a fitted blazer than a boxy cardigan, which my daughter liked because she said it felt more like “real clothes” than a costume. The sleeves are short, which is good for indoor school events; she didn’t get too hot running around.

The skirt is a simple black piece with an elastic waistband. No pleats, no zip, nothing special in terms of cut. It’s basically a plain A-line skirt that sits just above the knee. For a costume, that’s fine, but if you’re expecting a proper pleated school skirt, this isn’t it. The shirt is a basic white short-sleeve with a collar and a fake button-front look (it’s pull-on). The buttons are there for show more than function, which is actually easier when you’re dressing a wriggly kid early in the morning.

The tie is what makes it feel more like a character outfit. It’s red with white stripes/checks and long enough to tie a simple knot. It’s not pre-tied or elasticated, so younger kids will need help. Once tied, it stays in place reasonably well, but obviously it’s not as thick or structured as a real school tie. Overall, the design is simple but effective: nothing mind-blowing, but if you just need a clear book-character uniform that photographs well, it ticks that box.

Comfort-wise, my daughter is quite fussy: if something is itchy, tight, or too hot, she takes it off the minute she gets a chance. She wore this set for a full World Book Day at school — from 8:30 to 3:15 — and didn’t ask to change or take off the jacket once, which for me is a good sign. When I asked her after school, she said it was “like normal clothes, just a bit more dressy”, which is basically what you want from a costume like this.

The fit is slim but not restrictive. The elastic waistband on the skirt means it’s easy to pull on and off and it didn’t dig into her stomach, even after lunch and running around at break time. The shirt has enough room around the shoulders and underarms so she could raise her arms without feeling stuck. The jacket sleeves being short helps a lot; with long sleeves she usually ends up pushing them up and getting annoyed, but here she just forgot she had it on.

In terms of temperature, the fabric is fairly breathable for polyester. It was worn indoors most of the time, and she didn’t come home sweaty or red-faced. The material isn’t soft like pyjamas, but it’s not rough either. No scratchy labels, no stiff seams rubbing on her neck. I checked her skin afterwards and there were no red marks or irritation, so that’s reassuring if your kid has sensitive skin.

The only small comfort downside is the tie. Because it’s a real tie you have to knot, we had to do it tight enough so it wouldn’t slide down, but not so tight that it felt choking. It stayed put, but my daughter did say she noticed it a bit when she bent down. If your child hates anything around their neck, you might end up skipping the tie after the photos. Apart from that, I’d say the outfit is perfectly fine for a whole day of wear during events, but I wouldn’t use it as daily uniform because the fabric isn’t as breathable or robust as proper school clothes.

The outfit is made from a polyester and cotton blend, with polyester doing most of the work. You can feel straight away that this is costume-grade fabric, not the thick, sturdy material you’d get from a proper school uniform brand. It’s a medium-weight fabric with low stretch, so it holds its shape, but it doesn’t feel particularly premium. That said, it’s not the shiny, plastic-feeling stuff you sometimes get with cheap Halloween costumes, which was my main worry.

The jacket fabric is slightly thicker than the shirt and skirt. It has enough weight to hang nicely and not cling, but it’s still quite light. The inside isn’t lined, so you just get the back of the fabric and the seams. The stitching is generally okay — no big loose threads or holes out of the bag — but if you look closely, some seams aren’t perfectly straight. For occasional wear, it’s fine; I wouldn’t rely on it as an everyday blazer for school.

The white shirt is the thinnest piece. It’s a bit see-through in bright light, so I made my daughter wear a white vest underneath just in case. The cotton blend makes it softer on the skin than pure polyester, and she didn’t complain about itching or discomfort, even after wearing it for a whole school day. Same with the skirt: lightweight, slightly stiff at first, but it softened up after the first wash and didn’t feel rough.

One thing I noticed: because it’s mostly polyester, it’s quite easy to clean, but it also means it can get a bit static and clingy if you don’t use any fabric softener. After washing it on a 30°C gentle cycle and air-drying, the colours didn’t bleed and the pieces kept their shape. You do need a quick iron on low heat to smooth out the creases, especially on the shirt and jacket, but nothing dramatic. So in short, materials are clearly budget-level but acceptable for a kids’ costume that’s meant for occasional use.

Durability-wise, I went in with realistic expectations: this is a costume from a mid-range Amazon brand, not a premium uniform. After two full wears (World Book Day and a birthday party) plus a couple of try-ons at home and two washes, it’s holding up better than I thought, but you can tell it’s not made for everyday school wear.

The stitching on the main seams — shoulders, sides, waistband — is still intact, and nothing has come loose yet. The printed badge on the jacket hasn’t cracked or peeled after two washes on a 30°C gentle cycle, which is usually where cheaper prints start to fade. The colours on the jacket and skirt still look strong; the shirt stayed white and didn’t go grey or yellowish, which is always a risk with cheap polyester blends.

Where you see the limits is in the details. A couple of small threads appeared near the hem of the skirt after the second wash, nothing dramatic but it tells me the finish isn’t top tier. Also, the fabric on the shirt feels slightly thinner after washing, and if your kid is rough on clothes — sliding on the floor, climbing, etc. — I wouldn’t be surprised if you eventually get a small tear or pulled seam somewhere. It’s fine for occasional costume use, but I wouldn’t expect it to survive months of weekly wear.

For what it’s meant to be — a kids’ fancy-dress outfit for things like World Book Day, Halloween, book week and parties — I think the durability is pretty solid. It should easily handle several events and maybe being passed on to a younger sibling if you treat it reasonably. Just don’t treat it like a real, daily uniform and expect it to behave the same, because it won’t. As long as you keep that in mind, it delivers about what you’d expect for the price.

The costume arrives as a single set with all four pieces folded together: grey coat, white shirt, black skirt, and striped tie. No extra accessories, no wig or props. It came in a basic plastic bag, like most budget costumes, with a small label showing the size (120) and the brand name Koongso. Nothing fancy, but everything was clean and not wrinkled to death, which is already a win for something that’s been in transit from China.

Out of the bag, the colours are as shown: the jacket is a medium grey, the skirt is black, the shirt is bright white, and the tie is red with white checks/stripes. The badge on the jacket is printed, not embroidered, so up close it’s obviously just part of the fabric, but from a couple of metres away it passes for a school crest. My daughter liked that, she said it made her feel more like a “real” pupil from the story.

The size range on the listing is 100–150 cm, and I picked 120 because my daughter is about 118 cm tall. On her, the shirt length and skirt length looked right for a school uniform vibe: skirt just above the knee, shirt not riding up. The jacket is slightly fitted but not tight, so she could still move her arms freely. I’d say it runs true to size for height more than age; if your kid is tall or on the bigger side, I’d consider sizing up.

In terms of first try-on, she was dressed in under five minutes. The shirt is pull-on style, the skirt has an elastic waist, and the tie is a simple strip you knot yourself. There are no complicated fastenings, zips or hidden buttons to fight with before school. From a parent perspective, the presentation is basic but practical: you open the bag, shake it out, maybe quick iron the worst creases, and you’re good to go.
