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.

Bonjour,
Merci pour ce cosplay je l'apprécie , il est super beau le problème c'est que j’achète toujours les cosplay en taille M et ça me vas parfaitement la c'était grand, j’ai peu de poitrine donc le haut baille au niveau de la poitrine ( je vais me débrouiller pour serré le haut ) jupe un peu large mais c'est plus agréable comme sa et les froufrous au niveau du bas de la jupe c'est incroyable , les pinces sont magnifiques surtout les étoiles, les chaussettes sont trop serré pour moi !!!!
Encore merci pour ce cosplay !! 🩷
I have many cosplays from Uwowo but never had one fit so well! It was almost custom-made for me with the measures!The only downfall is that the sides in the chest are a bit low so it'll show the bra you're wearing so use a skin tone one or maybe don't wear one if you can.
