I can see everyone here is really into sport bras, but to tell the truth, I still wear standard bras. I'm a D myself (32D), and wearing sport bras, I end up with me all bunched up, overheated and, dare I say it, sweaty. Best fits I get are the Wacoal and lately tried Linaire, which worked out pretty good. I have a fair space between my two breasts and these brands give me the separation I need to stay comfortable. Wacoal makes a style that is a plain knit underwire that is pretty good for the summer. I think it comes with underwire or not, although being a D, I ALWAYS get an underwire. The witchy part is that Wacoal is not inexpensive - they run $30-50, depending. Hold up really well, though, and last ages, no matter what. I spent YEARS never seeming to fit into a bra decently until I found Wacoal...I'm a big believer in getting the right clothes for the right sport, but when it comes to bras, it's GOTTA FIT RIGHT!
