Size: 12 - but fits like a 6-8. See note below!!!!! ******* Definitely DOESN'T fit like a size 12!!! NOT A SIZE 12!!!!! I am 5'9 and 140 lbs. Please see picture of me trying the dress on. This fits me very well with maybe a-little extra room. So I would say this will fit you if you are a size 6-8. I'm also tall - 5'9 and the length is good. Mini denim dress with puff sleeves. Button down!!!! Color is a darker blue! New with tags!!!!! Excellent condition. NEW!! NO SMOKE HOUSE!!!!! Perfect for fall / winter!!!!!! :)
