These tights are typically higher than 40 Denier, meaning the leg cannot be seen through the material. Opaque Tights are warmer and more robust than sheer tights.
Over the knee socks are quite simply a pair of extra-long socks that extend up the leg, with the top traditionally resting just over the knee. Overknee socks are usually crafted from thick wool to provide a textured look that provides extra warmth, though this highly trend-led style often appears in a range of different fabrics and thicknesses. Often ribbed or knitted into a decorative pattern, over the knee socks are highly popular as an alternative to hosiery and are often worn to achieve a leg-lengthening look.
