The white window tank is a very fitted top and you might want to think about sizing up if you are between sizes and want a little extra room around the waist. The material is pretty sheer. It is also soft and very comfortable to sweat in. The window in the back tends to pop open (gape) when the shirt rides up. Overall, I think sizing up would allow for a more relaxed fit, but if you are feeling it, fitted looks great too!
Perfect for summer
Cute open back but I needed a larger size than normal
Love the window tank, it's perfect for showing off all those cute strappy and Sarah bras. I have a Large and it fits like a large.
