"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"
"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."
"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!"
"This crop is so cute and comfy, one of my new favourites! I'm 5'8" 135 lbs and the XS fits me true to size. No built in bra which I actually love. . . gives a little extra oomph when you have light support and makes it more versatile. I just wear covers below which works great. The fabric feels amazing and it's so flattering. I've been really impressed with CSB quality in general, my pieces from over a year ago still look just as good as the day I got them. Definitely a staple!"
"This top is great! Feels pretty supportive, and I love that it kind of looks like a halter but without digging into your neck."
"The bra fits nice and holds the girls nicely it's just, material is nice too. p"
