As someone who is larger chested, I have always struggled to find a white cami that won't show my bra. Every cami I have tried on has appeared almost sheer until I found this one. It has a light shelf bra inside which is absolutely comfortable while still hiding bra lines. In general the cami is very comfortable. The fabric is skin-tight, which I wanted in a tank top and does not roll up when you wear it. It is an essential cami to anyone's wardrobe.
