Quality Size and Cut
"Band wise it worked when I sized up to M (vs the size guide) but there is some loose space at the bust area... and in white as a result the bust area needs some smoothening out of the crumples."

"Love the Serenity Lexi Crop! The quality is great, the color is even better, and it’s really comfortable. I’m a 32C and sized up, but if you’re between sizes, I’d recommend sizing down. I definitely could’ve gotten away with the smaller size, but I personally prefer a more compressed, secure feeling in my sports bras. Overall, really happy with this one!"
"Love this bra! The cut is super flattering and sleek, and the fit is really comfortable while still feeling supportive. The fabric is soft, smooth, and feels high quality. It’s perfect for Pilates or Lagree but cute enough to wear with leggings outside of class too. Definitely one of my favorite CSB pieces!"
"would love to love this but i bought it in a size s, which is my usual CSB size, but its loose and my underboob kept showing as there was no support at the bottom of the bra. gave it to my sister and she loved it tho, would recommend to size down from your usual csb size if you are a smaller cup girlie."
"This bra is so flattering! The Chilli color is absolutely gorgeous, and the back design is my favorite part. It’s stylish, unique, and looks amazing during back workouts. The fabric is comfortable and supportive, making it perfect for both training and everyday gym wear. Definitely one of my favorite sports bras!"
"The color is so beautiful but unfortunately this crop didn’t fit me as good as I was hoping it would. It didn’t have support for my breast at the bottom and it fit loose instead of fitting snug to support the breast. I wore it once and my boobs we’re coming out at the bottom :/"
"Love this bra ! I would size down in the future (my first time buying a bra from here so was unsure on sizing) but can still wear for lower impact training."
"The design is so chic and quality is way up to standard!"
"Love ❤️"
"A decent garment; I’d give it an 80%. It could have been even better."
