I was worried ordering this because it didn't come with a size, but i couldn't resist. I figured if it was to small id give it to my little sister and if too big, my older sister. It fits perfectly. i am 24, 5'4, average weight. I couldn't be happier. i have a large chest and i was overly happy to see it fit perfectly. my little sister (12) wanted to try it on, it fit her perfectly too (weird that it fit... also, she is obviously small chested) It really is a one size fits all sweater which is very very odd to me because it looks just as good on one person as another. but if your bigger, i wouldnt chance it. but i could be wrong. i am ordering this in grey too and i cant wait to get it. ALSO i get so many complements on this sweater. It arrived way earlier then delivery date
