"Love the fabric and design. The scrunch in the back is not very comfortable and its a little bit tight in the waist. Good quality and performance"
"Love love love it. Very pretty and very good quality. I wish I knew the sizing better but when I got the right fit - it was perfect. The hidden scrunch was super contoured. So well made."
"This is by far the worst quality activewear I’ve ever put on my body. I’m 5’5”, 120 lbs, and very petite/slim — and somehow these leggings fit horribly. They give the most unflattering fit and are way too tight in all the wrong places. I normally wear a small, had to size up to a medium, and now even the medium feels too small to the point where I’d probably need a large. The sizing is completely off. Honestly, this brand feels like it’s made for extremely tiny frames or kids — not grown women."
"I love the Serenity Scrunch Leggings. They’re super flattering and the scrunch detail really enhances the shape in a natural way. The fabric is comfortable but still supportive enough for Pilates workouts. The espresso color is gorgeous and very easy to style with other pieces. These have quickly become one of my go-to leggings."
"places nice on body, fav activewear, bariety of range love this set"
"Cute leggings. I really like the scrunch and sheen of the fabric however they ran a bit small compared to my form leggings which are also a size small."
"Love the fit, color is very nice. Very soft, comfy, and flattering overall."
"I’m absolutely in love with my new CSB fitness outfit. The quality, fit, and design are truly stunning and make every movement feel even more confident and elegant. Starting tomorrow, I’m excited to begin sharing new content featuring their pieces. I can’t wait for you to see it. Thank you so much!!!â¤ï¸"
"I love the shape, the serenity are my favourite snactching fit and the scrunch is perfect. I always find it so flattering. It is an essential piece to my wadrobe, CSB leggings are my fav I can never go to another brand, they're truly so amazing and the essentials to my wadrobe."
"Feel of the leggings are great - love the material! My issue is the waistband rolls down constantly - in Pilates you have to constantly pull the band up. For the price just seems too expensive for this to be happening."
