Description

The SPANX Supersmooth Undie-tectable Thong delivers invisible shaping with a smooth silhouette under any outfit. Engineered with a bonded waistband that smoothes your core and elastic-free edges that create zero visible panty lines, this thong offers level 2 shaping that feels like a light hug rather than restrictive compression. The breathable fabric features a cotton gusset and quick-drying construction, ensuring all-day comfort beneath fitted clothing. Designed with full front coverage and a thong back, the Undie-tectable Thong combines core control with everyday wearability. Note that SPANX items fit slightly small, so sizing up is recommended for the perfect fit.
