I wore this a couple of times with a turtleneck underneath. There are no noticeable stains. I'm selling it because the size didn't fit me. It has a pattern all over and is very cute. The color is navy. The fabric is sturdy. It's stretchy. The following measurements are approximate, as they are taken by a素人 (amateur). Please understand that there may be some errors. Please use them as a reference only. Length: Approximately 56cm Sleeve length: Approximately 56cm Shoulder width: Approximately 37cm Width (armpit to armpit): Approximately 44cm I am also selling this on other sites. It may suddenly become unavailable. Thank you for your understanding. #Uniqlo #GU #Mujirushi #SamanthaMos2 #axesfemme #AmericanHolic #Nikoand #studioclip #GlobalWork #anySiS Color...Blue Material...Acrylic/Rayon (synthetic fiber) Neck...Crew neck/U neck Season...Autumn/Winter
