Sheer thigh high pantyhose can be both the finishing touch for an outfit and a sexy statement. Showcasing the legs, modern sheer thigh highs are termed 'stay up,' since they don't depend on garter attachments. Instead, they have a wide band at the top with silicone grippers to keep stocking in place. When deciding on a sheer hosiery, it's good to understand the denier factor, which is how sheerness is measured. The thicker the fiber the higher the denier, with 8 being the most sheer and 100 being the least sheer. Very low denier sheers are also called ultra-sheer. You'll find sheer thigh highs in classic colors like nude and black. Ivory and white are popular bridal items, while some brands offer interesting options like hot red.
