All trans woman we have one thing in common regardless of any other differences.
Its dang hard to find underwear that fits comfortably, is affordable, supports us as we need is feminine and is made to wear on a day to day basis.
There may very well be relief just over the horizon. Chrysalis Lingerie which according to the Daily Beast will be doing a grand opening this spring. Good! Its really hard for me, a 144lbs 5'8 transwoman with a "B" cup to find a bra.
