Briefs are easily identified by their elastic waistband, no leg and minimal coverage. They usually offer a Y-shaped fly in the front and have enough fabric to offer full coverage from the waist to the top of the thigh with complete coverage of the buttocks. Briefs provide excellent support and are less prone to bunching and rising than other styles. They’re an excellent choice for men who opt to wear tighter pants or low-rise pants. They are perfect for men who work at a desk all day, because they end in the natural crease between the body and leg.

Trunks are the newer style and offer the simplest silhouette, ideal for wearing under slim-fit trousers. They sit perfectly on the hip, a little lower than other styles, and are short in the leg, cutting across mid-thigh, which make them best for men with skinnier legs.” Take care with ‘hipster’ styles, warn the experts at M&S; they sit low, so work best with tucked in shirts. Or you risk an intimate breeze every time you bend down.
