Fits perfect , just as expected I love this type of jacket to fit my body & it’s like a glove. Not to tight , but not loose.Fits greatI read reviews on sizing up because it runs small, and that I can agree with it does run small. For me I am a small but decided to order a Large how most reviewers said and it fit perfect with a little bit of room to move around in, but it was not skin tight on me so I also think a medium would have fit as well. Maybe a tighter fit than the large but I think it would have fit me like a small if it was true to size. Overall I am still pleased with the fit and love how it flatters my body when I have it on, I am also 133lbs. :)Best purchase, in black and white. I usually wear xs, and I had to size up to medium. I would love more colors, vibrant red or soft pink, however, with color matching zipper.Buy with trust, highly recommended!For reference I am 5ft, 175lbs and bought an xl. I’m super self conscious of my arms and I’m currently at my heaviest so that doesn’t help. I bought these for the gym and I love it. Definitely size up.. these are tiny!! Im usually a size 10 and range between medium & large in shirts. Hope this helps!Its feels nice it thigh fitting but not thigh to the point to cant breath. Its so nice and give you a shape which i love! Definitely going to buy more!!!Size medium. True to size. Super comfortable for being a tight fit. The length isn’t too short as a crop - I can wear with any type of legging. Size C boobs fit in the zipper without being squashed. Overall great zip up for the price. Wish the material was a little softer so rated it a 4 star.
