"I’m in love with the butter yellow! It’s so pretty and the quality is great!"
"Really happy with these shorts. The fabric is soft and comfortable, and the invisible scrunch is subtle but still flattering. The 5” length feels like a nice balance - not too short, not too long - and they stay in place well during workouts. The Butter colour is also really easy to style. Overall, a great everyday pair of gym shorts."
"Honestly i ordered these in an xs which is my normal size and they were extremely small. I went to return them but somehow misplaced the tags, but i had already started the return process. I got an email saying I only had x amount of time to return my item, but i did not bother because i knew i could not return them due to their policy of needing the tags on. To my surprise a new pair in a size small came in weeks later and they fit great! I was so happy and will definitely be ordering again. They may have sent them as an accident but it has made me a long term customer."
"Fave fabric and shorts. Slightly see through because the fabric is light but with the right pair of pants they’re fine!! Gorgeous"
"The fabric was so incredibly smooth and supportive. My first product with the invisible scrunch and it hugged in all the right places. Butter yellow is such a great colour, especially with a tan. 5” is perfect length for me - I’m 155cm tall. I could have sized up for a more relaxed fit but wanted to feel supported in the structure and shape for my workouts"
"The perfect set. So soft, and not see through. I was hesitant on getting the light color but they are perfect!"
"The colour is stunning and the fit is so flattering. I've received so many compliments on these. I'm a pilates instructor so I teach, do pilates and weight training in these shorts and they're SO comfortable."
"The butter colour is so cute! I bought it with the ballet wrap and it's the perfect combo"
"love the fit and the color ! perfect for warmer weather"
"Butter shade is so lovely! 5” in the form also stays more in place. Only minus is since butter is a lighter shade, the double layer waistband shows off quite obvious against the legs being single layer."
