Sexy clothes for guys and girls from the 1980s king of denim.. In Short Guess has come a long way since the acid-washed jean outfits and 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-turning leather jackets and denim pieces. Halter tops meet low-waisted jeans, and red often meets black. In addition to stocking simple black pants and colorful, flattering tops, Guess has belts and purses for sale.
