Because I need a 28-30 band and a large cup, good sports bras are few and far between. The Panache sports bra (model 5021) has been my favorite. Adjustable straps, supportive enough for running, and it's even attractive, unlike some larger sports bras. It's quite expensive (the again, aren't all my bras? ), but Panache isn't usually excluded from sales (I'm looking at you, Freya!). I save my money during the year and stock up during the good holiday sales. Ebay is another way to save money, once you know the style and size you need. I've bought brand new bras there for half off before.

Sports bras used to be intimidating....until a thread here made me realize that I'd been wearing the wrong size (too large of a band and too small of a cup). Once I hashed out my correct size, bras have been far less stressful and far more comfortable.
