I have a little secret. Sometimes, I wear shaper-shorts (that's what I call them) under my skirts/dresses. It started a few years ago when I put on a few extra pounds and my thighs met each other for the first time in several years...maybe ever. I hated the feeling of my legs rubbing together as I walked. Hated it. So off to the Leggs, Hanes, Bali Outlet I went.
Now I proudly own 3 pairs of these brilliant shapers in nude, white and black. I'm back to a comfortable size and my legs no longer touch (to the point of discomfort), but I still wear the shaper-shorts fairly frequently. It's nice having the extra coverage - knowing that if the wind blows, or if I have to get in/out of a large vehicle, or I'm walking up stairs, no one will see anything that shouldn't be seen.
