This tank top is cute and does the job but it’s a bit of an odd cut. You definitely cannot wear this with just a regular bra unless you don’t mind pretty much the whole thing showing on the side. I prefer to wear normal bras for support, I have trouble finding a good sports bra to wear on its own that supports my breast’s and is still comfortable and flattering. I wore this today with a regular bra and a sports bra over it and it looked fine. It works for walks, runs, working out, and being around the house. I just wish the cut was a little different and it’d be perfect. Sizing is comfortable- I’m usually a large but bought this in a medium and it fits well with room. Overall I am happy.
