I personally think it runs a bit small... The fabric around the neck doesn't stretch much either... I felt it was tight when putting my head through... But it's very cute when worn ♡ I don't think there are any noticeable stains. [I apologize if I missed any stains.] Please refrain from purchasing if you are sensitive to used items, as I am a private seller. Please consider this item understanding that it is a used children's item! (※I wore it until around 3 years and 6 months old.) Thank you for looking. #MirrorBay #Baby #Baby
