WHAT CUSTOMERS ARE SAYING

I love this Contrast Tank so much and can’t wait to get other colors. The material is great quality and very soft and comfortable, while having great support.

Aislynn Wilson

These bike shorts feel and look amazing on. I love the crisscross design in the front. They feel so buttery soft and fit like a glove! Perfect sizing.

Melissa B.

These shorts are the cutest!! I’m 5’3 150, and I bought the medium. I love the biker shorts underneath. Feels tight, secure, and I’m not worried about showing anything. I also got them in white, and now I’m getting the mint!

Jessica Villarreal

Material is thick and soft with the perfect amount of light compression. I was worried about the crossover waist hitting at an unflattering spot, but they are surprisingly flattering. The length is perfect. I am 5’8” 125lb and small fits well.

These bras have quickly become a fave. Super comfortable and of course the sewn in pads. Cannot get any better than that. I need all the colors.

Elevate Ribbed Bra
My favorite day 1 piece

I love this bra. It’s soft, comfortable, supportive and versatile. I like it better than the lululemon flow y because of the sewn in bra pads. It fits true to size. I did not find the thin strap to be problematic but maybe if you are very large chested.

I am very surprised with these leggings

I am very surprised with these leggings. I thought I would not like them due to the ribbed material (I thought of those very thick ribbed fabrics) but these are so soft and nice. While the material is not thick, it’s also nice enough for no see through. I think these are the most comfortable leggings. Sewn in underwear is a plus.

Alessandra

Material is thick and soft with perfect amount of light compression. I was worried about the crossover waist hitting at an unflattering spot but they are surprisingly flattering. The length is perfect. I am 5’8” 125lb and small fits well.
