Had designer Rogan Gregory been at the “soft opening” last Friday of his new R Store, and not in bed with a 101-degree fever, he probably would have described the shop -- like the manager did -- as “his lab.”

“It’s where he can introduce all the designs he loves that other retailers would shy away from,” explained his stand-in, Rachel. Like tissue-thin T-shirts with holes in them. Or super-narrow “Funnel” jeans with no visible stitches (what Rogan himself wears everyday). Or $700 rigid selvedge “Bow” jeans with hidden rivets, triple stitching, and silk lining. There’s one pair for each size, and they also come in white.

But the store, which also houses Rogan’s suit line called A Litl Betr, isn’t just about clothes. With its heavy brick walls, black paint, and low-hanging aluminum lamps, the space (designed by Rogan himself) is a shrine to rare -- if not exclusive -- arts and crafts. There are shelves full of out-of-print books on subjects ranging from Art Nouveau lighting, to how to sleep better. And there are tables devoted to stylist Kate Young’s artful side projects, such as unusual corkscrews, wooden bangles, and stationary cards that read “dear true heart.”

There’s an enormous glass vase filled with women’s underwear designed by Dustin Horowitz, using men’s shirting; delicate gold jewelry by Scosha; and, coming soon, vintage objects and jewelry culled from all over the world by Cassie Mercantile -- like huge indigo-dyed African Fetish necklaces.

But the real focus of the shop, as well as its foundation, is Rogan’s clean-lined furniture collection, which debuted last month at Barneys. The hammered metal tables and modernist wood and leather chairs are made from recycled materials riddled with imperfections. Exactly the kind of pieces you’d expect from a man who likes his T-shirts artfully tattered.
