It is silly to have pricey shapewear sewn into pantyhose, since hosiery is obviously too delicate to last long. However, my bodycon dress was so clingy that when I tried separate shapewear, the seams and cuffs of the shapewear were visible through the dress--so I was forced to use a one-piece like this.)I looked very smooth but my derriere was not flattened, either. Thanks, Spanx--you saved the day. I put it on with great care not to create runs, and I wore it for hours and walked up and down the fashion runway in heels, but there were no runs or damage at the end of the day. I washed it gently and it's ready for another use. But let's get real: I won't expect too many wears out of it. Panyhose never do last.
