Ralph Lauren Women’s and Home

Prince of prep Ralph Lauren has added some serious grandeur to the already-swanky Madison Avenue with his new women’s and home-goods shop, housed in a stunning Neoclassical French mansion. You’ll feel more like a dinner-party guest than a customer while perusing handbags, footwear and R.L.’s first-ever fine jewelry line in the opulently decorated ground floor, outfitted with crystal chandeliers, Persian rugs and antique furniture. Ascend the grand staircase to the second floor, and brace your wallet for premium apparel and accessories from the runway, plus silk and cashmere sleepwear and made-to-measure services. The third level offers the voguish Black Label, clean classics from the Blue Label, the vintage-inspired RRL collection and the sleek, sporty RLX line. We spotted staples such as calfskin wallets with brass stirrup details ($245) and leather belts with polo-team-scene buckles ($375); then we horsed around in the “Create Your Own” area, where you can custom-design polo tees ($80). For tableware, decorative accessories and linens, continue upward to the fourth floor, where price points are attractive to both the impoverished noble (alpaca and wool tartan blankets, $195) and the heiress of largesse (suede-trimmed cashmere blankets, $995). Dudes shouldn’t get disheartened: Across the street is Ralph Lauren men’s shop, in the newly refurbished and equally grand Rhinelander Mansion.
