"I’m absolutely in love with the Chilli color! It’s the perfect shade of red—vibrant, flattering, and even prettier in person. It makes every outfit look more stylish and really stands out in the gym. If you’re thinking about getting this color, don’t hesitate. It’s gorgeous!"
"The compression is great I love the feel of the fabric and matches the vibe of any top"
"Color is 10/10 on these chilli shorts! I got these with the scrunch because the regular was sold out, was worried about the scrunch but it is very subtle so I liked it more than I thought! Perfect length"
"These shorts are such a standout! The scrunch detail is super flattering and gives the perfect sculpted look, while the high-waisted fit feels really supportive and secure. The fabric is soft, stretchy, and comfortable, and the no front seam makes them feel so seamless to wear. The hidden waistband pocket is such a handy bonus too."
"great material and cute color! surprisingly no camel toe despite being very fitted which was a super pleasant surprise! Shorter than imagined but that's my fault for not paying attention to description."
"I am obsessed with the shape and scrunch of these shorts. They fit so well on the body. They are the perfect length and coverage! I would highly reccomend! The colour is also perfect"
"Love all my scrunch and invisible scrunch shorts from CSB!"
"I love this colour, coverage is great, a beautiful selection amongst the other options and places."
"The scrunch in the back is so tight and a little crooked Shipping took forever"
