It's interesting to see that even young celebrities with perfect bodies are wearing the modern equivalent of girdles - SPANX - when they want to cinch the waist and slim the hips.
But no one uses the word 'girdles' anymore. These evolved girdles are called 'slimming shapewear'.
Here's a photo (taken by Splash News) of Beyonce Knowles in what appears to be SPANX tummy control nylons. It's made of a special spandex weave giving "seamless, leg-shaping support." And it's designed "with a soft, nonbinding waistband."
This photo of Beyonce will probably be a bigger boost for the SPANX company than any advertising they've done in their short but successful history to date.
