UNDERCOVER Denim Trousers Black. Jun Takahashi again flexed his ability to masterfully combine distinct themes by incorporating fetish-inspired designs into everyday wear that has a twist. These denim trousers are made from different fabrics, featuring a denim fabric on the front and a soft polyester fabric on the back. Key features include a regular fit, mid-waist, button closure, zip-fly, five-pocket construction, and pleats at the front and back. Made in Japan.
