SPANX Undie-Tectable Thong (SP0115). Trust Spanx to come up with a totally sleek thong that actually helps control the tummy, bans V.P.L. and is invisible under clothing! Made of nylon/spandex. Bonded waistband helps flattten tummy. Reinforcement stitching where waist meets crotch lining. Seamed sides lie very flat under clothing. High rise covers more of abdomen. Fused-in 100% crotch for comfort. Ultra-smooth nylon/spandex microfiber knit feels like a second skin. Smooths you under your skinny jeans without “smushing” your derriere. Very “cheeky,” minimal rear coverage.
