I am 5'3 127-129 lbs depending on the day of the week. I always get xs in FN denim jackets and have never had a problem. Unfortunately, this jack missed the mark. It's a beautiful jacket don't get me wrong but it's huge and I don't normally mind if a blazer jacket is a little oversized, but this thing swallowed me and looked clownish. It even looks oversized on the model, but I thought maybe she sized up but no that's how the xs looked on me and it ruined the look I was going for. Also, the shoulder area was a little tight, so the body part is huge, but the shoulder part is a little tight which was weird. It's a shame because it's a really nice jacket, it just needs to be a smaller cut. So, if you are thicker cutie then you may like this jacket but it's a no for me and I returned it. hope this helps.
