Trousers (or "pants" in North American English, sometimes "slacks" in more formal or older-fashioned usage) are an item of clothing worn on the lower part of the body and covering both legs separately (rather than with cloth stretching across both as in skirts and dresses). Historically, as for the West, trousers were the standard lower-body clothing item for males since the 16th century; by the late 20th century they had become extremely prevalent for females as well.
Trousers are worn at 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 lycra. Trousers are also known as pants. The different types of trousers are cargo pants, jeans, shots, quarter pants and corduroy pants. All told, jeans inhabit a peculiar place in any boy`s wardrobe.
Slacks are also a popular category found in a boys cupboard since slacks are really nice to wear, are comfortable and look good on boys. Today bell-bottom trousers are really nice to wear and they fit on all boys. Though this is a very old fashion but such trousers are popular with the teenagers.
