I had a dress emergency yesterday, and that 'necessity' made me 'invent' something useful and wonderful.
I needed something to smooth out my tummy and thighs. So, here it is, 4 hours before I have to leave for a funeral, July, hot and I had too many kids to run out and get a satiny thing to help me. So, I took an old pair of pantyhose and chopped them off at the knee. This gave me smoothness from the waist to the knee (read as 'no chub-rub), and wasn't too hot. Plus it was a lot cheaper than a Spanx and I didn't have to go anywhere to get it.
Don't toss holey pantyhose - you never know when you are going to need them.
