Mayfair, London, England

Manly and refined: There are no two qualities more attractive in menswear. And that's exactly what Albam Clothing offers. It's all about no-nonsense, well-crafted classic clothes and accessories with a subtle nod to retro icons like Steve McQueen in the 1970s. There's also a "master barber" named Mr Natty on site at this Mayfair boutique, who will spruce up your locks so they're as sharp as your new duds…and sell you some manly hair products along the way.SHOP NOW >

If a designer shows at London Fashion Week, most likely they can be found at the Mayfair-based Browns Focus. This younger, hipster sister to the more established Browns Fashion across the street (42 years and counting!) is also where they often host trunk shows attended by Alexa Chung and the London social set. Color and cut are two key things for their wares, which are all displayed on black mirrored walls: Cue the floral lace peacoats by the hyper-talented Simone Rochas, crazy-mad printed dresses by Ostwald Helgason, and Anna Laub's architecturally cool sunnies.SHOP NOW >

Nope, it's not a flea market: Rei Kawakubo of Comme des Garcon, turned an old Georgian building in Mayfair into a wonderfully ramshackle, beautifully-disheveled six-floor store that has more in common with, say, the Tate Modern. Everything is arranged like one big art installation—the changing rooms are even formed from repurposed portable toilets—and every six months "tachiagari," which means "new beginnings" happens. Designers come in to totally reconfigure the Dover Street Market space and set out new goods. The prices can be as steep as a piece of art, too, with all the Alaia, YSL, and Celine. But that shouldn't stop you from checking it out: There's also CdG's inventive collaborations with Marimekko, dozens of art books, and other wallet-friendlier knick-knacks that make every visit a delightful wander.

Jewelry stores generally come in two varieties: Old-fashioned fine jewelers (Henry Winston, Tiffany) or the cheap and cheerful (Claire's). Kabiri, however, deftly occupies the spot right in between, serving up cool, cutting-edge baubles for all thicknesses of wallet. At the Mayfair boutique, you'll find glass bead bracelets by Nikki B that are handmade in Chile (and priced at under $100) right alongside super-pricey (and hefty) Maharaja-era inspired black diamond and ruby earrings set in black gold by Parisian-based Gaydamak. And so, so much in between.SHOP NOW >
