A panty girdle is a type of shapewear that helps to smooth and shape the lower torso and hips. There are several synonyms for this undergarment, including control briefs, high-waisted shaper, shaping shorts, and compression shorts. Control briefs offer a similar level of support and coverage but typically have a higher waistband and offer more coverage for the stomach area. High-waisted shapers, shaping shorts, and compression shorts are also designed to smooth and shape the lower body but may have different levels of compression and coverage depending on the specific style. Ultimately, the choice of shapewear will depend on personal preference and the specific needs of the wearer.
