Retro Sunglasses

One of the worst Instagram scenarios is stumbling across someone's outfit you absolutely love, only to realize they didn't credit any of the pieces they're wearing. Every night this week, that's exactly what's happened to me. I've scrolled past an array of It Girls wearing those perfect Kurt Cobain-inspired sunglasses and (unfortunately) found that they're either vintage or from a secret shopping destination said It Girl just isn't ready to reveal. Lucky for us, that search is finally over: We've uncovered a hub of affordable retro-inspired shades and we just can't keep it to ourselves.

Giant Vintage is, indeed, a never-ending collection of bug-eyes, cat-eyes, and every shape in-between. Whether you've been combing the internet for clear aviators or haven't found that perfect pair of tinted lenses yet, Giant is sure to come through. Here's what we love: Most of the frames cost no more than $30; you can shop by decade, silhouette, or by top sellers; and the site uses real people as models. That way, you can get an accurate feel for how the sunglasses actually look on someone's face.

Sure, the quality may not be let you keep these frames for the rest of your life, but for stocking up on of-the-moment shades, we're willing to let that slide (especially since Giant has tons of styles we haven't been able to find anywhere else).

You never want something until you can't have it. So, each week in The Sell-Out, we're getting the scoop from your favorite retailers on what's selling like crazy. Watch this space to find out what everyone's buying, sign up for wait lists, and keep tabs on restocks.

We're used to shoes, bags, and even jeans selling like crazy. Some pieces, especially when they're part of a celebrity collaboration or a limited-edition collection, just can't stay on the shelves. But when a style of sunglasses goes completely out of stock every single time it drops, you know it's got to be good. And with shades being one of the toughest things to shop for online (in our opinion, at least), it's rare that we come across a pair so many people swear by.

Enter: The Quay X Desi Perkins High Key aviators. The collection, which originally launched in June, saw the style sell out in both black and gold color ways (and in record time for the brand, no less). On October 15, Quay re-released the Encore High Keydue to an overwhelming outpour of requests, which likely has something to do with the shades' popularity among people like the Kardashians, the Hadids, and Jennifer Lopez (to name a few). But the brand didn't stop there. Now, the shades are back for a third time.

These modern aviators feature oversized mirrored lenses, metal frames, a double bridge, and adjustable nose pads, and are offered in black, gold, and blue. At this time, the styles have now also been released to actual brick-and-mortar stores as well as other retailers — we're told Zappos and Nordstrom have the largest stock. Seriously — people are not messing around when it comes to getting their hands on a pair, so make your moves by shopping them ahead (along with some similar styles, in case they're wiped by the time you're reading this).
