This unabashedly sexy take on the classic back-seam ups the ante (and your nocturnal a-game). Slinky and perfectly sheer, with a plated opaque sole, traditional raised heel, and an unexpectedly sassy graphic bow detail on the boudoir back seam these stay-up thigh-highs are 100% business in the front and pin-up in the back. The smooth stay-up cuff is lined with a stay-put band of silicone making these the perfect thing for layering under pencil skirts and cocktail dresses alike.
