This is a cute blouse from Ralph Lauren. The back buttons are also adorable. The sleeves are puff sleeves, a design that is typical of Ralph Lauren. It's 24M, so it's probably equivalent to 90cm. There is no stretch. I don't see any noticeable stains, but please understand that this is used. Ralph Lauren white shirt, size 24M, with a collar, giving a lovely impression. - Brand: Ralph Lauren - Size: 24M - Color: White - Design: Collared, button closure Thank you for looking.
