London

From Harrods to the high street (and everywhere in between), London may just be home to the best shopping across the pond. Don't forget to leave plenty of room in your suitcase!

Bimba & Lola

I always get compliments on anything I wear from Bimba & Lola, a Spanish label that’s new to the U.K. Shop here for bright, colorful separates and really cute, not-too-expensive bags. – By Justine Fairgrieve, CEO of RelativeMO

Westfield London Shopping Center, Ariel Way, plus other locations, 44-208-743-8528, bimbaylola.es

The Box Boutique

The playfully opulent interior (lamps made from bowler hats, neon furniture) at this shop run by a pair of Russian sisters plays second svirel to the way-glam shoes and accessories. Find dramatic sunglasses, Swarovski-studded Ugg boots, and Ruthie Davis stilettos fit for a night at the nearby raunchy cabaret nightclub that share's the store's name.

45 Maddox St., 44-207-499-4277, theboxboutique.com

Boxpark

Boxpark is the world’s first pop-up mall. Made out of old shipping containers, each “box” is its own little self-contained store, gallery or café. I go to the Marimekko shop for its cups and tea towels. - By Justine Fairgrieve, CEO of RelativeMO

2-4 Bethnal Green Rd., 44-207-033-2899, boxpark.co.uk

Broadway Market

Come on a Saturday, when people-watching is at its peak. Queue up for Violet’s éclairs, then peruse the handmade knickers, Karin Andreasson’s delicate, ’20s-era jewelry and Kate Sheridan’s bright canvas carryalls.

Charlotte Olympia

It’s not surprising that the daughter of a model designs teetering heels. But Charlotte Dellal’s (Olympia is her middle name) saucy six-inch versions are shockingly comfortable, and even her espadrilles and flats capture her irresistibly quirky-cool take on ’40s glamour.

56 Maddox St., 44-207-499-0145, charlotteolympia​.com

COS

H&M’s sister label, Collection of Style, excels at chic, Jil Sander–meets-Marni basics at High Street prices, which makes this a great place for workwear that’s cool but not too-cool-for-corporate. The dressing rooms are fantastic: spacious, with a 360-degree-mirror setup and soft, flattering light.

22 Regent St., plus other locations, 44-207-478-0400, cosstores.com

Darkroom

Everything here is a play on scale, materials and form—the store’s essentially a rec room for accessories- and interiors-loving grown-ups. Authentic African design pieces sit alongside the house label, inspired by the Dutch de Stijl movement (think Piet Mondrian).

52 Lamb’s Conduit St., 44-207-831-7244, darkroomlondon.com

Elphick's

Visit Columbia Road on Sundays for the amazing flower market, and stop in here for super-affordable (£12 and up) pop screen prints by artists (including owner Sharon Elphick) from all over Europe.

160 Columbia Rd., 44-207-033-7891, elphicksshop.com

Folk

Find a sublime edit of pared-down, sharply cut offerings from small European labels like Sessùn, Acne, Humanoid and Won Hundred. Folk’s own line of ankle boots and pretty platform sandals should satisfy any Rachel Comey shoe lover.

53 Lamb’s Conduit St., plus other locations, 44-208-616-4191, folkclothing.com

Gillian Horsup

Once you find this stall (fourth door on the right down an alley, very back of the basement floor), you’ll feel like you’ve struck gold—and you have. There are vintage Lacroix earrings, Dior brooches and piles of English art deco and midcentury sparklers, much of them under £100. Tip: Pay cash and she’ll likely knock off a few quid.

1-7 Davies Mews, 44-207-499-8121, gillianhorsup.com

Harrods

The only place for great customer service in London is Harrods. Yes, it’s touristy, but its staff is perfection at walking you through a challenging purchase, like buying jeans or bras. Plus, they carry every designer in the world. – By Justine Fairgrieve, CEO of RelativeMO

87-135 Brompton Rd., 44-207-730-1234, harrods.com

Late Night Chameleon Cafe

The most revolutionary store in London, LN-CC, is in a very run-down area, but it’s worth the trip. The interiors look like the Millennium Falcon’s from Star Wars—that is, if it were full of art books and clothes from Haider Ackermann and Toga. You have to make an appointment to get in, but you won’t feel pressured to buy. - By Justine Fairgrieve, CEO of Fashion PR

18 Shacklewell Lane, 44-207-275-7265, ln-cc.com

Luna & Curious

There are sweet sailor-inspired blouses by Colenimo, the most inventive bottle planters and decorative dishes aplenty. The zebra- and butterfly-design false eyelashes—inspired by Chinese paper cutting—will blow your mind.

24-26 Calvert Ave., 44-203-222-0034, lunaandcurious.com

Maison Trois Garcons

While the astounding selection of affordable French Regency furniture and ornate trinketry at this café-cum-shop may have you wishing for a bigger suitcase, don't be too dismayed: the necklaces, or an embroidered purse, will definitely fit in your carry-on.

45 Redchurch St., 44-787-964-0858, lestroisgarcons.com

Persephone Books

This bustling little publishing house reprints work (fiction mostly, but also cookbooks—all of it witty and modern) written by women between 1914 and 1950. Most volumes are lined in patterned paper duplicated from fabric of the era.

59 Lamb’s Conduit St., 44-207-242-9292, persephonebooks.co.uk

Rose Bakery

It’s fun to people-watch at the Rose Bakery. Located on the top floor of the Dover Street Market (the cutting-edge retail store), it’s full of fashion-industry types who come for the casual atmosphere, delicious carrot-and-ginger juice and healthy specials. – By Justine Fairgrieve, CEO of RelativeMO

17-18 Dover St., 44-207-518-0680, doverstreetmarket.com/rosebakery

SHOWstudio

Nick Knight's unassailably cool fashion website comes to life in the company's new Belgravia HQ, where the first floor plays host to a rotating array of curated gallery shows. Think: Daphne Guinness' collection of custom Gareth Pugh, full-body bondage gear by Una Burke and bespoke Shaun Leane baubles, alongside a killer array of coffee table tomes.

19 Motcomb Street, 44-207-235-7680, showstudio.com

START

The edit of edgy designer labels local (Christopher Kane, Markus Lupfer) and international (Carven, Sonia) is unmatched by any other in the city. Make this shop number one on your list.

42-44 Rivington St., 44-207-729-3334, start-london.com

Strut

Most of the goods at this vintage store have an ’80s slant (think loads of Vivienne Westwood and Balenciaga) while much of the decor was salvaged from the iconic ’60s Mary Quant store on Carnaby Street.

2B Ada St., 44-207-254-8121, strutbroadway.blogspot.com

Topshop Oxford Circus

This global flagship has, hands down, the absolute best of the brand. It’s also loud, crowded and crazy. Here’s our guide to getting the goods without losing your mind.

Wolf & Badger

A crumpet’s toss from Dover Street Market is this slick space spotlighting indie British brands in homeware, objets d’art, fashion and accessories.

32 Dover St., plus other locations, 44-203-627-3191, wolfandbadger​.com

Wah Nails

Even my most conservative friends can’t resist a manicure at WAH Nails—there are about 60 different designs to choose from! I recently got a psychedelic daisy mani to match my Erdem skirt. – By Justine Fairgrieve, CEO of RelativeMO

Suki Waterhouse's London City Guide

My favorite shopping neighborhood is Primrose Hill. It has a quaint village-like feel.

When looking for vintage, I enjoy wandering around Brick Lane. The area has an amazing flea market too—I bought my first-ever vintage piece there, a Sonia Rykiel coat I adore.
