I bought this at Shimamura! The collar is attached, so it stayed in place while I wore it! This is an outfit that got me a lot of compliments at daycare. The pants underneath were easy to match with anything ⭐︎ I'm selling it because my child has outgrown it. I am a private seller, so there may be some overlooked stains, dirt, fading, or fraying that are not very noticeable. Please purchase with the understanding that this is a used item! #Sweatshirt #Shimamura #Size90
