When Sarah Larson Levey started Y7 Studio [1] in mid-2013, a chain of Vinyasa-style [2] facilities with dark lighting and a "give-no-f*cks," love yourself attitude, she wanted it to be about inclusivity. That aspect was, for her, missing when she started yoga. "I don't care where you're coming from, I want you to walk in that space, and I want you to have your own experience," she told POPSUGAR. The yoga flows are all conducted in candlelit, heated rooms with no mirrors, and the classes are paced to the beat of music (yes, even Cardi B [3]).

The studios are meant for everyone, even if you haven't tried yoga before, Sarah explained. That's why, for Y7's first-ever collection, she chose to work with Girlfriend Collective, a women's activewear brand true to inclusivity both in its sizing and message — its website states front and centre [4], "We believe health and wellness come in many shapes and sizes, and that representation matters."

Like the stripped-down atmosphere in Y7 Studio, Girlfriend Collective's clothes are simple and feature solid colours, but still stand out. Plus, everything is made from recycled water bottles, and the fabric is buttery soft. "They have such a broad range of sizing, and I think that's so important as fitness and boutique fitness is getting more and more ingrained into everyone's daily life," Sarah said. "Working out is not just for the athletic person anymore."

The line features four classic pieces: two sports bras, biker shorts, and compressive leggings, all in extra small to 2XL. Prices range from $45 to $75. Ahead, check out the Y7 x GFC collection. Find it online [5] and at all Y7 Studio locations in NYC. The message is simple, Sarah said: "It's, 'You have a body. You should move it. And there should be clothes to fit that.'"

Y7 x GFC Paloma Bra in Black

This Paloma Bra [6] ($45) comes in sizes extra small to 2XL. It's longer in length, so it can double as a top (it's the little black dress of activewear!).

Y7 x GFC Petite Paloma Bra in Ivory

The Petite Paloma Bra [7] ($45) comes in the same sizes as its black counterpart and is more cropped. Both are made for medium-impact workouts.

Y7 x GFC Bike Short in Smoke

The Bike Short [8] ($55) comes in extra small to 2XL. Biker shorts are "in" (didn't you hear? [9]), so grab a pair of these sleek beauties and get to moving!

Y7 x GFC Compressive Legging in Black

You can't go wrong with a pair of black leggings. The Compressive Legging [10] ($75) from this collaboration is available in sizes extra small to 2XL, like the bike shorts, and are high-waisted.
