Shop It To Me Threads
Like an online personal shopper, this site sorts through everything that's currently on sale from your favorite brands and in your size. Looking to scoop up something from 3.1 Phillip Lim—but only if it's priced at under $150? Maybe you're after some Isabel Marant—but have a strict $300 budget to stick to? Threads is your go-to. You can also "follow" certain trends or styles—nice if you're looking for something specific, like summer sandals or a chambray shirt.
Walk In My Closet
Forget about buying new things—ever lose track of the pieces you already own? Walk In My Closet functions as a virtual extension of your own wardrobe, allowing you to photograph and catalogue your clothing and accessories collection. Share looks with your "clique"—or just keep them to yourself—and shop a selection of global showrooms straight from the site. Sick of something you already own? WIMC's resale section lets you sell gently-worn items—or pick up vintage finds from fellow members.
Obsessed with an item you've found online—but want to get it at a better price? Add PoachIt's bookmarklet to your browser, and click it when you're on a particular product page. You'll get notifications if and when the piece goes on sale, plus any coupon codes you might be able to use immediately. You can also use the site as a shopping tool in and of itself—click on "Deals," and you'll find tons of currently-marked-down items worth snagging.
Hukkster is a price-tracking site that operates using a bookmarklet you add to your browser bar. Click the "Hukk It" button when you find something you love from a certain e-tailer, and you'll be alerted when the price drops. Though it doesn't work with every single site under the sun, Hukkster is linked with some of our personal favorites—ASOS, J.Crew, Net-a-Porter and Shopbop among them.
The RealReal
As its name implies, The RealReal is a place to snag authenticated, pre-owned luxury goods from labels like Chanel, Hermès, Prada and many more at steep discounts (as in, 90 percent off). There's no risk of buying fakes here—everything on offer has been stylist-selected and checked for quality by pros. Like Gilt or Moda Operandi, everything's presented via several-day-long flash sales, with new designer merch added daily.
Founded by BFFs (and former Lucky Girls) Eleanor Ylvisaker and Ferebee Taube, FEYT's the place to browse designer goodies from a wide variety of e-tailers. Add favorite pieces to your virtual closet, rating items you like and dislike as you go. FEYT will use your own ratings to decide which products to recommend to you in the future. Use pieces in your closet to build and save looks, then browse the site's Featured Closets section to see what industry insiders (models, stylists, socialites and more) are loving right now.
Part of the fun of international traveling is discovering far-flung boutiques from every corner of the earth. Farfetch combs the globe for the very best shops and puts them all online, allowing users to browse one-off finds from places you'd normally need a thousand-dollar plane ticket to access. With inventory from boutiques including A'maree's (Newport Beach, CA), Work in Progress (Monaco) and Stockholm Market (Stockholm), you may never book an actual vacation again.
Another site that brings boutique shopping online, Shoptiques seeks out local shops from around the world that carry one-of-a-kind pieces. Fill your cart with finds from multiple stores—even those located on different continents—and ship them straight to your door. We love the "Talk to Stylists" feature, which allows shoppers to learn how to wear seemingly tricky items—or to find the perfect look for an upcoming event with the help of a pro. Plus, Shoptiques offers trend stories and mood boards to help you get inspired before your next big purchase.
By following all your favorite brands and stores on Lyst, you sign up for new product and sale updates as they happen. You can also follow bloggers and fellow Lyst users to see what they're coveting and considering. It's great for tracking items you've got your eye on, but also perfect for getting inspired.
This app claims to be "part store, blog, magazine and wish list," but we prefer to think of it as a shoppable Pinterest. Browse tons of cool items—fashion, technology, home décor—and click on on the ice cream pop-shaped "Fancy" button to indicate things that you, well, fancy. Get it for iPhone or iPad at the App Store, for Android phones and tablets at Google Play and for Windows Phone here.
