"Favourite style of CSB sports bra. So flattering yet supportive"
"The Serenity Sierra Crop is so flattering and comfortable. It has the perfect amount of support for workouts while still feeling really lightweight and easy to wear. The fit is secure without feeling restrictive, which makes it perfect for training sessions or everyday movement"
"The most flattering crop. Love the two tone. Perfect sizing"
"I love this for my hot yoga and Pilates classes. I’m an instructor and I like that it stays in place. I’m small chested after a explant surgery and I feel like the bra is flattering. Dries quickly so I don’t feel gross and cold after class."
"I looooove this crop. I have worn them out, gone up sizes, down sizes, and I always repurchase no matter where I'm at in life. I haven't worn a bra in years, I've just worn the Sierra. So good. Love love love."
"Obsessed is an understatement. Both me and my husband are obsessed with this. The support is chefs kiss, the chest looks fabulous during any and all workouts. I even go running on this top. The white details give it an elevated look. Fits true to size. One of my favorites from CSB!!"
"I’m always receiving compliments for this one, and people often ask where it’s from. It’s great support and suitable for all kinds of movements, from yoga to HIIT."
"Love this bra, especially for a heated sculpt class. It's surprisingly supportive and super flattering."
"It was very flattering. The size is just a bit tight to my liking but it looks and feels really nice. I love this brand <3"
"Super sexy top! I just had a baby so I ordered larger than my normal size and the top kept everything in place! I would recommend for low impact workouts where you want to feel sexy but also comfortable!"
