"I love the crossover design, so flattering. The fabric is great for the gym, compressive but comfortable. The rich navy color is very pretty."
"These have quickly become my go-to leggings for lower body workouts. The crossover waistband creates such a flattering shape, and the material feels flexible and supportive at the same time. They hold up so well during training and still look really sleek styled casually after the gym."
"Love these tights ! Very thick material which is very supportive, just find the back could be a bit higher up my hips/waist as I find I need to pull them up quite often during a workout. Love the front cross design though!"
"Flattering fit, jazzy waistline. Something a little bit different. Serenity is a beautiful fabric. If I had to choose, I probably prefer the regular serenity fit."
"I love these leggings. The fabric is very soft and the design is super flattering on my bum/waist. I am also planning to purchase the same style in the crossover navy shorts and buy the cropped jacket too so it all goes together in a set. Highly recommend! Only thing is that the fabric is quite warm so I plan to wear the tights for my winter workout outfit rather than during summer."
"These will make a good staple but they’re not very exciting… they’re not as dark navy as pictured on the website and I find now that any non-scrunch variety feels like they are constantly slipping and need to be pulled up! These are okay but I’m definitely not in love and wouldn’t buy any others in this style"
"Leggings fit perfectly in the same size, but bra sizing is inconsistent across styles even when ordered in the same size."
"Very good quality and high support"
"The high-waisted fit stays in place all day and the fabric is soft but still supportive. I got an S ( 165cm / 48kg) and I think xs would be more fitted. So I’d say size down."
"Fit like a glove beautiful fit flattering in all the right places crossover is slimming"
