Great fits are trousers in rayon or wool crepe, jersey, or gabardine.
Find the right length of trousers by trying the shoes you will wear with them. Trousers that are too short or too long make you look outdated and rob you of presence. Trousers should hit the top of the heel, so you can see the shape of the shoe and get that elongated line. Trousers with lining give an easier fit and helps hide bulges. Tall people can carry cuffs at any width.
