With off-duty models like Gigi Hadid and Kendall Jenner championing the style, athleisure is arguably this year’s biggest streetwear trend. Designers and celebs alike were quick to infuse the just-heading-to-cardio look their design. One of our faves? Beyoncé’s Ivy Park.

Is it the Flashdance-esque choreo in a shadowy gym? Is it the unbelievable shape that the singer/actress is in? Is Yeezy’s catchy song? We’ll never know. But we love this video and look–even though we would probably never leave the house in this costume.

This costume choice is so much less basic than the dancing girls emojis, don’t you think? Also, avocados are reallly good for you.
