I don’t find Dita to be itchy, but also prefer unlined bras. As for underwear, i try to always wear a matching set. You never know who is going to see you undressing, and I always feel sexier and more feminine when everything matches.
If you are around Chicago or Detroit try Busted Bra Shop.
Wacoal and Chantelle are always great choices in 36C. I used to be 36b/c now 38c. Need to loose 10lb but both brands still work. If looking for something sexy try Dita Von Teese.
I am also a wacoal fan. Retro chic has great shaping and support. Also sexy.
I'm basically not straight, she definitely did something for me. You have great taste in women! She is sexy as hell, and you know she would tell you exactly what she wants.
I followed your link here just to say hi.
