Serving the World’s Best Clothiers for Over 20 Years Trinity Apparel is a wholesale manufacturer of custom clothing, shirts, casual wear and outerwear founded by custom menswear veteran Wen Nance. When the journey began in 2002, custom suit vendors did not prioritize customer service and the design options offered were limited and uninspiring. Trinity is unique in that we were founded by Clothiers for Clothiers. We are successful today because we form partnerships with our Clothiers and prioritize their success. We also lead the industry with our unparalleled variety of options and fabric selection.
