Dress socks

Dress socks are an article of dress clothes specifically for men. Traditionally, sometimes come in checkered patterns, and come in colours like black, brown, blue, and gray, but recent fashion trends have seen different patterns and colors appear. Dress socks are worn in accompaniment to dress shoes and they are also used in formal wear when worn in accompaniment to a tuxedo. They can also be worn in accompany to casual wear like jeans.

They also come in a variety of heights. They come ankle high, mid calf high (the most common), and over the calf. Dress socks have also been known to slip down the leg, causing the wearer to have to constantly pull them up. In the past, men would buy garters or sock suspenders to help this, but with the introduction in the 1960s of better elastics such as spandex, it is mostly unnecessary now. Some men with larger calves may still need the extra assistance of garters to keep socks from slipping.
