"I sized up in these shorts and they fit great! The waistline is flattering and the shorts don’t ride up. I run and lift in these and I don’t have to pull them back down. They are my go to shorts!"
"The fabric is smooth, sculpting, and offers just the right amount of compression to help you feel supported during your workout. They're comfortable enough to wear from the gym straight into the rest of your day, and the crisp white color looks so fresh"
"Adore the chilli red color, these shorts look amazing. I did size up from my usual CSB size and I probably didn’t need to because they are slightly loose but I didn’t want them pressing on my thighs too much."
"These Serenity Shorts 4'' in Navy are just the perfect piece to add to your casual/athletic outfits! I love the way it stretches and hugs the body, also buttery soft material! If only they had a warehouse in Europe and thus reducing shipping costs I'd be buying these shorts in all colors! XS was the best fit!"
"These shorts are so snatching and I find myself grabbing them over other pairs so often! They’re perfect for literally everyday, I go to Pilates in them, go out for coffee, run errands, they’re such a good buy and totally worth it. True to size!"
"my glutes looks sculpted and it does not ride up as much, way better cutting compared to the 6inch"
"I was told about this brand and when they came to Miami for the pop up my girlfriend and I made it out and she got a ton of stuff. After that we have made two more orders and even her friends are now buying because of her"
"I absolutely love the Chilli set from CSB, it’s easily my favourite colour. It’s incredibly flattering, especially the sports bra, which fits really well and feels great during workouts. I wear it regularly for my strength training sessions, and I like it so much that I’ve since bought it in several other colours!"
"Love these, thought they might be too short but are perfect. Bought an S instead of XS just incase they were too tight."
"I love these shorts so much and they just look perfect with the chilli tank top. The material is super nice and soft, the quality is amazing. I’ve washed them a couple of times and they still look like new. Also, I have to say that even though my waist is already small, they make it even smaller, it’s crazy! They are also very stretchy which makes my workout very comfortable"
