Best Answer: Boxers tend to be loose and shaped like shorts. Briefs are more of a snug fit and have no leg. A compromise between the two styles has been developed, called boxer-briefs that has qualities of both. Boxers are great for feeling some freedom, but briefs are good for keeping support. I like boxers for when I am relaxing but briefs when I run.
Trousers (pants in North America and Australia) are an item of clothing worn from the waist to the ankles, covering both legs separately (rather than with cloth extending across both legs as in robes, skirts, and dresses).In the UK the word pants generally means underwear and not trousers.Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment.rousers are worn on the hips or waist and may be held up by their own fastenings, a belt or suspenders (braces). Leggings are form-fitting trousers, of a clingy material, often knitted cotton and spandex (elastane).
