I used this for a sibling outfit on Halloween. There are some pills, but I think they should come off with a pill remover. I dressed my 2-year-10-month-old in it, and the top fit perfectly, but the bottoms were a little big. Personally, I thought it might be small for a 4-year-old. The size is listed as "tod," and according to my research, it's for 【80-100cm (3-4 years old)】. The pants are fluffy and voluminous, so it was very cute to see their little bottom wiggling as they toddled around. There's also a top to go with it on another page! (If you purchase, I'll discount the shipping a little m(_ _)m)
