I purchased this for my child's Halloween costume at a children's center and it was worn about three times. Originally, it was a 4-piece set including the costume, hat, pants, and tights (yellow), but I'm not including the tights because they became noticeably pilled after hand washing. Also, the neckline was quite low, so I used safety pins to close it. The fluffy pants are cute, and I think they would look good on both boys and girls. The size is S, which is about 90-100cm. My son wore it when he was about 2-3 years old. The following is quoted from the product's HP: About this product Set includes: Costume + Hat + Pants Cute! Donald Duck costume has finally arrived! The fluffy material expresses Donald's fluffy bottom cutely. Note: There may be differences in color and material texture between the actual product and what you see on your mobile device or computer.
