Hailey Bieber's date-night style is as enviable as it gets. No matter what vibe she's going for on any given night on the town, she looks cool and effortless—including when she appears to possibly have forgotten her pants. That was a joke, of course, as pantsless outfits are a trend that celebrities, in particular, love. And the boots she chose for the night actually made the trend a bit more wearable.

Bieber's outfit consisted of an oversize black ACNE Studios sweater and a pair of Coperni Western boots.

Western boots are one of the biggest boot trends of the season—especially elevated knee-high pairs, so it's hardly surprising that the always trend-forward Bieber is wearing them. The boots grounded the no-pants outfit, giving it more of a low-key, cool-girl look than heels would've.

Pantsless outfit or not, I'm fully convinced that I need a pair of knee-high Western boots STAT. Scroll on to see Bieber's date night look and shop a few of the pairs of chic Western boots I'm deciding between.
