At first when I tried this on, I thought I had purchased it in a size too large. I'm a size 10/12 and I bought a size large. It felt more like a fitted tank top then something that was going to smooth out my sides. I then put on a fitted top over the cami and found it did in deed smooth out the sides very well. It does squish your bust together a little bit, but it will give you a great cleavage while doing it! It took wearing it for about 12 hours and a 2 hour car ride before I had any issues with it riding up. It wasn't uncomfortable in any way.

I am definitely buying more!
