Marshall Field's and Victorias Secret, and Title IX Sports for workout bras.
As a member of the "well endowed" club, bras are very important to me. My absolute favorite is a style by Wacoal, which I got at Field's. It's underwire and fabulous. Victoria's Secret has some good ones as well, but I don't always love all of their stuff -- it's more hit and miss with them.
I have heard that Frederick's of Hollywood has good bras, and I've also been wanting to check out the Bra Smyth catalog -- they're online at
www.brasmyth.com and they have a great selection.
I prefer underwire. As for panties, I love the second skin satin hipsters from Victoria's Secret. They are so comfortable. I wear a thong when I must (I HATE VPL more than is probably normal) but not if it's not absolutely necessary.
And that's more than anyone ever wanted to know about my underwear...
