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 arrived. The large square collar can be worn both front and back, completely changing the look depending on how you wear it. Of course, you can also remove the collar and wear just the dress, so you can enjoy a 3-way style for parties or depending on your mood.
