Size up
While I like the concept, it’s not true to size. I cut the tag off thinking this fit well, as I wear 38G in most HSIA bras, I found that throughout the day this rode up and gave me “quad-breast.” It also broke the skin on my back where the anti-slip rubber was on the band. It has potential, maybe if you size up with band and cup.
