Young Teen Girl In Tight Pants

Trouser-makers can finish the legs by hemming the bottom to prevent fraying. Trousers with turn-ups (cuffs in American English), after hemming, are rolled outward and sometimes pressed or stitched into place. The main reason for the turn-ups is to add weight to the bottom of the leg, to help the drape of the trousers.
• Fly
A fly is a covering over an opening join concealing the mechanism, such as a zipper, velcro or buttons, used to join the opening. In trousers, this is most commonly an opening covering the groin, which makes the pants easier to put on or take off. The opening also allows men to urinate without lowering their pants.
Trousers have varied historically in whether or not they have a fly. Originally, hose did not cover the area between the legs. This was instead covered by a doublet or by a codpiece. When breeches were worn, during the Regency period for example, they were fall-fronted (or broad fall). Later, after trousers (pantaloons) were invented, the fly-front (split fall) emerged. The panelled front returned as a sporting option, such as in riding breeches, but is now hardly ever used, a fly being by far the most common fastening. Most flies now use a zipper, though button-fly pants such as Levi's 501 jeans continue to be available.
