Emma Corrin and Rami Malek go together like white linen and summer vacation.

On Sunday, the couple was spotted strolling Rio de Janeiro's Ipanema beach looking like the personification of an automatic "out of office" responder.

Corrin, who seems to be taking a quick break from the Deadpool & Wolverine press tour (the actor plays supervillain Cassandra Nova in the upcoming film), donned a pair of striped boxer shorts — one of this summer's hottest trends, thanks to our recent obsession with wearing underwear as outerwear.

Corrin paired their laid-back bottoms with a simple knit sweater and what appears to be Lemaire's cult-y croissant bag. The cherry on top? A pair of Birkenstock Bostons, which Corrin clutched in their hand during while enjoying the sand.

Malek's vacation 'fit was just as unpretentiously stylish as Corrin's. The Bohemian Rhapsody star opted for an ivory button down and matching, high-waisted trousers with the cuffs casually rolled up.

His shoe of choice: the tried-and-true adidas Samba, a pretty perfect counterpart to Corrin's classic Birks.

Corrin and Malek, who went public with their romance last September, aren't often photographed together — but when they are spotted, their couple 'fits never fail to impress.

Whether they're grabbing coffee or attending Paris Fashion Week together, they're always sartorially in-sync.

Off the red carpet, both have a penchant for timeless, tailored basics mixed with sporty touches. On the red carpet, however, they know how to pull out all the stops. Corrin, in particular, has been lauded for their audacious event dressing.

Over the course of the Deadpool press tour, the actor has sported statement-making 'fits from Miu Miu, Schiaparelli, and Saint Laurent.
