This is a petit main shoulder ruffle set-up that I purchased 2-3 years ago (o^^o) The size is 100, and it's made of denim! It's thin denim, so it's not too hot for summer ♩ I have too many clothes, and it's become too small for my child, still with the new tags attached... It's been stored in the bag it was purchased in, but it's been kept at home, so please refrain from purchasing if you are at all concerned (>_<) I am also selling other children's clothes, so please take a look if you'd like ♡ Branshes Slap Slip Apres les Cours Breeze Zara any FAM
