A crew cut is a type of haircut in which the hair on the top of the head is cut relatively short, graduated in length from the longest hair at the front hairline to the shortest at the back of the crown. The hair on the sides and back of the head is usually tapered short, semi-short or medium. A very short crew cut is sometimes referred to as a butch cut or buzz cut. A long crew cut is referred to in the US as an ivy league crew cut or ivy league. A typical ivy league might be graduated in length on the top of the head from one and a half inches at the front hairline to one half inch at the back of the crown.
