About Trouser Socks:
Trouser socks are a type of hosiery which features an extended cuff that generally reach the calf, or just below the knee, to cover the lower leg in occasions where this is exposed when wearing trousers. Trouser socks are usually made from lightweight materials in subdued colors such black, grey or brown or checkered patterns such as argylesocks. Trouser socks are generally designed to coordinate with trousers but recent fashion trends have seen novelty patterns and colors appear.
