What's better than one Pilates queen? *Two Pilates queens.*

BFFs that sweat together stay together — well, that's at least the vibe we're getting from Kendall Jenner and Hailey Bieber's LA Pilates class hangout sesh. The girls showed off their enduring friendship and styling chops as they made their way to the mats — and we got front-row seats to their latest contrasting, fall fashion offerings.

Miss Jenner tends to favor classic pieces that scream "off-duty supermodel," with her recent workout 'fits including chic biker shorts and legging sets (all from her fave athleisure brand, ofc). This look starts with her iconic base outfit —Alo's High-Waist Rise Legging in black and Airlift Intrigue Bra in white — and ends with a couple of key accessories. Nike's Air Vapormax Plus sneakers in black, white crew-height athletic socks, and a sheer, cropped long-sleeve t-shirt take the look from basic to boujee. To carry her essentials, Kendall wears a spacious black pebbled leather shoulder bag. The Kardashians starlet finished the look off with a pair of rectangular sunnies, mini gold hoop earrings, and a black fleece vest from The North Face.

For Mrs. Bieber, a more earthy and neutral approach was taken with her workout gear. We know all too well how much Hailey loves her thrift finds (see her graphic baby tee and sporty tank top), which is why it's no surprise that she's decided to wear a retro jacket from Worn Vintage. The distressed, stone grey of the coat compliments her taupe TNAButter Mini Bra and TNAChill Atmosphere Flare Hi-Rise Leggings from Aritzia, adding to the chill, ~cool girl~ vibes. Just like Kendall, Hailey paid close attention to the accessories. The Rhode founder wore Prada's Fussbett Sharling Sandals, The Row's Iris Small Bag, Oval Sunglasses from Balenciaga, and gold hoop earrings.

Kendall and Hailey's outing comes just days after Jenner's ex-brother-in-law Kanye West called out Bieber. After Hailey spoke out in support of Vogue editor Gabriella Karefa-Johnson, who voiced her opinions on his controversial new Yeezy line, which included "White Lives Matter" apparel, Kanye took to Instagram to express his feelings towards the model. According to Entertainment Weekly, in a since-deleted post responding to Hailey's criticism, Kanye called Hailey, "nose job Hailey Baldloose," telling her husband Justin Bieber to "Get your girl before I get mad."

This isn't the first time that Kendall has shown subtle support for her friends, as she recently liked Tweets from Jaden Smith detailing why he walked out of Kanye's Paris Fashion Week show.
