Waist cinchers come in a variety styles from high-waisted thongs to a classic girdle style. All will do what they're meant to do--create a shapely silhouette that accents the waistline. For an hourglass shape without muffin tops or other bulges, a waist cincher is ideal under form-fitting outfits. Some are styles like the corsets of long-ago, with boning and hook-and-eye closures. Other styles of shapewear are shaped like girdles, complete with detachable garter belts. The thong back waist cincher is a modern take, trimming the midriff and creating minimal panty lines in the back.
