"Short than expected but love the fabric and the color"
"Gorgeous pants"
"The scrunch is flattering, yes, but it seems to dig in a little between my butt cheeks. Not in a way that is too uncomfortable, but you can certainly feel the scrunch when you sit down. Waistband very solid. Clearly a good design for workouts"
"All of my fitted active shorts are from CSB. I just know the material and the fabric are always gorgeous and high quality. They just feel expensive and so buttery on the skin. Size PSA though: I'm a size 8-10 and generally fit a small in most brands but in CSB I'm a size large in all their activewear: shorts and tops so defs keep that in mind. I honestly think it's just from how form fitting and skin hugging their material is which isn't a bad thing you just need to find your right size."
"Length is great, nice material! Waistband feels solid. Does ride up a little but overall very comfy, highly recommend. True to size as well."
"Thought these would be too small looking at them when they arrived but they fit perfectly! Super comfy"
"Shorts are super flattering. Love the length on my height as well (161 cm)."
"Love the activelux Fabric! This is my favourite fabric it snatches you in"
"Activelux is definitely on the tighter side for waist and other than that I don’t feel the difference with serenity. if you want the scrunch to be less obvious on the body go for a tighter fit so the scrunch area is more stretched out."
"Obsessed with these shorts - wear them to the gym, to pilates, on walks, to go out, basically all the time! super comfortable and flattering. Activluxe generally runs a little smaller for me so the M was just nice and fit comfortably. Super versatile and cute pair of black shorts!"
