The designer earned his rep dressing up traditional basics with luxurious fabrics—think denim made with pima cotton—and for his first-ever suiting collection, he took a similar approach. The line only comes in minimalist black and gray (each available in a three-piece version), but is augmented by cashmere fabrics and smart detailing, from functional buttonholes on the jacket cuff to interior pockets with vertical (rather than horizontal) openings. (That should make silencing your ringing cell phone during dinner a snap.) Of course, a guy who sells $350 jeans ain't giving you suits on the cheap: They'll set you back between $2,500 and $4,000 when they hit Bergdorf's and Barneys this July.
