CSB's Serenity Leggings in Navy are highly praised for their compressive, sculpting fit and flattering look. Customers love the amazing quality, perfect compression, and buttery feel of the Serenity fabric. The high-waisted design and hidden waistband pocket add to the appeal, though some recommend sizing up due to the leggings running small.

"These leggings are a perfect fit, I finally have the experience of high quality active wear. I sized up one size, perfect fit. Very happy"
"Very high quality! In fact, everything I’ve bought from CSB has been really durable and soft. I almost kept a top that fit me properly just because it felt so good haha I’ve had multiple workouts and washes, and these leggings have passed the test of time. I’m going to be making another order this week!"
"This legging did feel more compressive on my body, but I didn't feel too tight or uncomfortable. It's a bit thinker than my Form leggings, and I think it would be great for colder seasons. So far so good!"
"Serenity is my favourite fabric from CSB. It’s incredibly flattering and supportive, and perfect for workouts if you like that “hugged-in” feel. The compression really helps you feel secure and held in place. For sizing, I’d recommend going up one size. I’m usually a small in other activewear brands, but I wear a medium in Serenity because it runs tighter than their other fabrics like Form."
"I love the fabric. I ordered the S and accidentally received the XS but customer service took care of the issue so quickly. The navy is a staple color and one of my favorites"
"Love any and every serenity leggings. Please never discontinue it 🥹. They’re my all time favorite leggings!"
"Absolutely love these fights, fit so well and the fabric is very good quality."
"Feels so nice on the skin, and super flattering as well. Definitely size up from your usual size"
"i have bought two pairs and i swear by them. super flattering and comfy. fabric is so soft and stretchy asw!"
"I love these leggings!! They are so secure, not sheer, hold me in, and stay in place! I typically am I size small and have found a medium is better for me in serenity as opposed to freedom. These are so cute and my go-tos. No pilling after multiple washes and wears in intense workouts."
