This is a Samantha Mos2 one-piece dress. It's made of a very soft, fleece-lined material, like sweatshirt fabric. It has side slits, so it would look good worn with leggings. It's been worn once, so it's in good condition, but please be aware that there may be some small, inconspicuous stains. The size is free. Shoulder width: 57cm Sleeve length: 37cm Length: 91cm Width (underarm to underarm): 57cm Slit: 34cm (approximately)
