Size Information Notice
Size Information Notice
1. About Our Size Chart
Please always check the size chart in the product description before placing your order.
Most of our costumes follow Asian sizing. If you are uncertain, we recommend choosing one size up.
Our models are mainly wearing size M for reference.
All dimensions are measured manually. Please allow a 2–3 cm deviation.

*The cup may change for different costumes.
2. Why Cosplay Sizes Feel Different
Different cutting standards: Cosplay costumes often include structured parts such as padding, bust cups, armor, or collars, which do not stretch like daily wear.
Body proportion differences: Even if bust/waist/shoulder measurements are the same, the fit can vary depending on torso length and body shape.
3. Additional Notes
Not all measurements are listed in the size chart (e.g., torso length or certain detailed parts). If you require additional size information (not including Collab Series), please contact our customer service.
A costume not fitting perfectly does not mean it is defective—variation is normal due to cosplay-specific design and sewing.
4. About Uwowo vs. Collab Series Sizes
Costumes with the white Uwowo logo (Collab Series) use size charts provided by our partners, and we cannot change those sizes.
Costumes with the red Uwowo logo (Uwowo Original) usually come in sizes S–3XL, following our in-house standards.

How to make note>>>>>

I got three amazing cosplays!!! I put some extra other than top three and they actually look at them! Although they only fulfilled one of my top three they included two i also wanted so im really happy with it!! (:
I give 3 stars because their customer service remains very pleasant. the sizes were respected except for 1 cosplay where I found myself with xl, and so too big for me ... the accessories are to glue ourselves with strong glue ... I also found myself with a tshirt, although it is a lot 3 cosplay I do not even have the reference that is on it :/ none of my wishes were granted so I spent 130 euros for 2 cosplay including 1 not my size
While it was great they followed my ‘wish’ which added a star to this review, the quality of the costumes were sh*t. Wrong gloves sent, damaged goods, not fitting correct pieces? I reached out and got a small refund so it added two stars but get better
I didn’t have much hope for mystery boxes but Uwowo granted my wish and I was so happy! I got bunny guizhong!! Also a hilicurl and a green jacket. Overall not bad. Will buy again if given the chance!
Sadly even though I put my size in the note I got two cosplays, which were three sizes smaller, but my wish cosplay was in my size luckily. Definitely would have wished that the size was looked after correctly and not chosen randomly too
