At the gym and for every day. Top itself is roomy and draped nicely. Bra is made for flat chested women. I ordered a large. I am chesty. It made my breasts flat. But everything pushed out under my armpits so it looked like I had breasts out the sides of my body. I would have to go at least to a 3x to make it work. Then the top would be way too big. I wish companies would realize that not all women who work out are flat. Some of us are size medium or large with 38eee bras. Not 3x with 38eee bras.
