This bra has several really good reviews so I had high hopes for it. It didn't work for me. For the record, I am a 40DD, so maybe it's just the size. It did seem to separate very well. And it has a type of material that keeps the straps in place - that's nice. But there was something about the back, it felt like the back strap was not wide enough or something.. Just didn't feel comfortable for me.
