My end goal for this cami was to smooth me out more so than to suck me in dramatically and I wanted to be able to breathe and move comfortably in it all day at work. I am 5’ 1” tall, approximately 170lbs and a size 10-12 or a large in most clothing brands. I ordered according to my measurements which put me at a size 2X in this cami. I was a little nervous that it would be too big but knew I could exchange or return it if necessary. I actually like the fit, tho. It’s easy to get on by stepping into it and it holds its shape all day and after multiple wears, which was another thing I was concerned about. It’s comfortable, has light compression so I’m getting some smoothing without feeling strangled. Hitting me at mid hip it’s plenty long enough, didn’t cut into my squishiness and make a dent and I wore it under pants so I didn’t have any problems with it rolling up but I’m not sure how it would stay in place with a dress or other clothing that wouldn’t hold it down. I may be able size down one size to get a little more compression but I’m not sure it would be as comfortable.
