Just that really. I wear Panache Tango on a day to day basis but I need a bra to go under a one shouldered bridesmaid dress. I need to buy online ideally as don't have masses of time to go to Bravissimo to try on. I also have a mid sized M&S and Debenhams close that I could go to. And I'd really love it to cost as little as possible as it will most likely only be worn once. Any suggestions gratefully received, I am late 30s with 2 dc, it has been a LONG time since I wore a strapless bra!
