Skinny jeans may come and go but when it comes to men's jeans, a straight leg cut is always in. Whether it's an Armani light wash, a printed Moschino trouser or a distressed DSquared2 jean you're looking at, the basic shape will see you through. No matter what your style, a simple straight leg cut in denim is a closet staple that will work with any look. Dress up a smarter version with a shirt and blazer or keep it casual, the classic denim cut is a basic failsafe of menswear. You can't go wrong with a straight leg jean.
