I basically only own/buy the Natori feathers bras. They fit me perfectly and the 30 band runs a tiny bit small, so even after stretching it still fits (I'm 28-29" at the band). This "contour plunge" version has sliiiiightly smaller cups, which I worried about at first, but they've softened and stretched a bit with use and don't seem too small anymore. It helps that the edging is a flexible lace that doesn't dig in and create bulges if the sizing is a tiny bit off.

Quality is great - I still have the first of these that I bought about 5 years ago. It's definitely past its prime but works fine on the smallest band setting and the cups have kept their shape well. I'd say these last a solid 2-3 years before they start to show noticeable wear and stretching. Definitely worth the price.
