Sexy clothes for guys and girls from the 1980s king of denim.. In Short Guess has come a long way since the inverted triangle trademark. But one thing hasn't changed: Sex is still the main appeal of this brand. Skinny girls and fashion-conscious guys favor the head-urning leather jackets and denim pieces that still double as casual work-wear. The chain's reputation for quality has apparently withstood the test of time. In addition to stocking simple black pants, leather jackets and colorful, flattering tops, Guess has belts, purses and sexy shoes for sale.
