Wear Matching Sunglasses

You know what they say: Couples who dress together, stay together. Just kidding — no one says that. But, we have an inkling it's true ever since seeing Zayn and Gigi Hadid wear matching his-and-hers shades last month. You may be used to seeing the couple in coordinating looks on the red carpet or on social media, but even when they're apart, their sunglasses keep them together. Cue all the awws.

The duo's pair of choice is the "Ward" style from the New Orleans-based (and CFDA/Vogue Fashion Fund winning) line Krewe. Gigi — who's no stranger to a bold fashion statement — sported the matte black color way with bright blue-green reflective lenses in New York City on December 8, while Zayn stuck with a clean and classic gold-and-black version only a few days later. What's more, Kendall Jenner is in on the trend, too (yup, she's like that third wheel who's never really a third wheel because they're all #besties) — she was spotted wearing the same pair as Zayn in LA at the end of last month.

But, sunglasses fit for models and pop stars don't come cheap: These have 24-karat gold-plated hardware and will set you back anywhere from $275-$295. Still, we're already getting outfit ideas from this stylish trio, and it seems like the Ward sunglasses go with just about everything. Click on to see their looks and shop the frames for yourself, and since Valentine's Day will be here before you know it, maybe scoop some up for your S.O. (and your bestie), too.

Your next casual all-black-everything look has met its sunglass match.

Zayn sports his with a crewneck pullover and a padded jacket for an equally cool off-duty ensemble.

Kendall sticks with the classics with her Krewe sunnies, donning a camel sweater and some vintage Levi's.

From Halsey's version, which perhaps looked the closest to an actual, traditional underwire undergarment, paired with a trench coat-esque skirt, to two different Cyrus' getups, the abs-baring trend was enthusiastically embraced this evening. It wasn't just a somewhat edgy styling decision for the occasion. There was a pragmatic rationale for the minimal styling up top, too: it was very hot, as a couple of stars noted, like presenter Nicole Scherzinger, who bemoaned the sticky temps on the step-and-repeat.

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.
