Columbia Women's Just Right Fleece Jacket - Lightweight Warm Zip-Up for Outdoor Activities, Hiking & Casual Wear

I love this hoodie! It is very cozy & well made. such a flattering cut, i am very impressed and recently bought 3 of them. I am 5' 7" & about 115 lbs., and the small is a very good fit. I can have a T-shirt layered underneath and it's not too tight on me but it's a nice flattering cut, not boxy or loose in the wrong places like some fleeces are. an x-small might be good for someone my size that wants a tight fit. personally i don't like shirts too tight & since the cut is so feminine and nice you don;t need it to be skin tight it looks great anyway. so for me small is perfect. but i know some girls like their shirts very tight, if so then maybe x-small is better for you. (note, I do have one in a size medium. it was the first one i ordered & i was too lazy to send it back. it is still wearable but not quite as cute/flattering cut as the others because it is a much looser fit & just a tad too long for my taste. i like the length of the small better) oh, I have one of the fast trek zip up as well and i love that too. I think i'll get more of those. i have a north face masonic hoodie and while it's cute it's not as cozy and nice as these columbia fleece's, in my opinion. :)
