I agree with Steph the Girdles make sence for a bad back when driving, but the bra, it looks to me that he is wanting to express his ultimate femme desires a little more.
While I do not wear a girdle, when I was on vacation Last March, I did find some nice waist cinchers. I wore one home for the whole trip, ( 800 or so miles ) and found it did help my back as well and now wear one whenever i have a long distance to travel. As for the bra, I love to wear one too, but that is to express my femmine desire, and the good feeling it gives me.
