Dress socks come in a variety of heights. They come ankle-high, mid-calf high (the most common), and over the calf. Dress socks have 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 correct this until the introduction of better elastics in the 1960s such as spandex, thus rendering it mostly obsolete. Although some men with larger calves need extra assistance of garters to keep their socks from slipping.[citation needed]
