I don't think there are any major stains, but this is just my amateur assessment. I've worn it for a year. Rosarymoon Square Collar Knit Dress Rosarymoon's classic balloon sleeve knit dress has been slightly redesigned, and a new version with a detachable collar has been released. The large square collar can be worn on either the front or back, and the image can be completely changed depending on the direction it is worn. Of course, you can also remove the collar and wear the dress simply, so you can enjoy a 3-way style depending on the occasion or your mood.
