Knee socks are the classic feel-good style of women's socks, perfect under trousers, jeans and longer skirts. When colder weather comes, wool, wool blends and thicker cotton socks can keep you toasty warm. For a polished, classic look, try opaque or semi-opaque trouser socks. These are usually made from a combination of nylon, spandex and other modal blends. They're offered in traditional colors, like black, chocolate and charcoal. Styles range from a plain weave in basic colors to ribbed, textured and patterned. For fun, try wild neon stripes, bright argyles or or lively polka dots. Chunky cable socks and ribbed styles combine warmth with a classic look. Most knee socks come to just below the knee, although over the knee styles are popular too. These long over the knee socks are great with high boots.
