Perfect shorts
"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!"
"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!"
"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"
"The fabric is the softest and most comfortable ever! Such high quality and perfect for lifting, pilates, yoga, errands, literally everything! I need in every color!!"
"Beautiful color and fit. I’m pretty short at 5’1. I find the shorts to be a little short but not too bad. (25/26)"
"True to size , I love them, so comfortable. Outline your butt , they rise up a little on the thighs cause they are short but not a deal breaker"
"Great basic to have. Super tight and form fitting I recommend sizing up. I am usually XS next time will order S for shorts!"
"Super tight, but I use it with the tank so it gives me more snatched look, its a great combo with the halter tank, and the length is great, I like it very short so I just roll it a bit, Serenity is thick, so if you don’t like it snatched get a bigger size, I’m an true xs and it fits cool for me (I’d love it more if it were a bit less high rise cause I’m 163 cm tall)"
"Great quality!"
