Love this top. I got it in black and attended the HITT class. It provides good ventilation as the mesh provides a lot of air flow without looking too skimpy. I am almost 40 years old, no need to show too much. It also doesn't ride up when doing floor work because I can tie it up securely.
I got the white top and it fits well. It feels like heaven on the skin because it is so silky. The mesh is also very comfortable and doesn't itch. I love the design as it covers well yet it makes you look good, not frumpy.
