Switch (2011)

The main actress takes her top off from behind,turns sideways ,turns on the shower and we see her side breast for a brief moment.

In another scene,the main actress takes a shower standing up in front of a mirror and both breasts are seen.(Since there's a mirror,we actually see her breasts twice in the same picture.)

In a later scene,the main actress is in a bath.We have an over the bath scene where her two breasts are seen. Once she gets up,her leg hides one of her breasts but as she moves,part of the second breast also becomes visible. She puts on a towel but as she takes it down to reach for a shirt, her two breasts are briefly seen.
