I was hoping to use these as a sports bra for light activities like riding my bike or lifting weights. These are very comfortable, but even for light activities, they aren't supportive enough. The pictures don't really show it, but the straps aren't really straps. It's like they took a little tube top, laid it down flat, and just cut roughly with scissors into the sides. The "straps" are just flaps of fabric without any stitching, so I think they are pretty low quality and will probably rip sooner or later. I guess the best use of this bra will be to wear it as a strapless bra (tucking the "straps" back down under your armpits) for tank tops in the summer. Overall, I wouldn't recommend buying them.
