Wearing it every day, everywhere! Obsessed

I paired it with the pink padded top and honestly felt like a total tennis babe! The fit is super flattering, not too short, and moves perfectly on the court. The fabric is soft but supportive, I’ve worn it for both tennis and running it’s that cute. Definitely a must-have set! 🎾💗 We’ll done Belsize

Love this set!

The PINK color is spot on and super flattering! These were squat proof and moisture wicking. Im 5'1 and 115lbs and a small fit great. I am small chested and the top did not disappoint! You need this added to your wardrobe.

Great for Pilates and aerial

Lovely leggings, feel and look amazing and are really good for silks as the airbrushed fabric gives a little more grip

Butter soft, great support and flattering too

Couldn't b happier with this Matching Set - the high waist on the leggings flatters, while the crop of the top lists nicely - Im no spring chicken, at 48, but the set is hugely flattering on - supportive in all the right places, and excellent fit and ever so soft. I actually bought several 'sets' thinking I would keep just one... Ive kept them all!!! LOVE

Stunning 🤩

Honestly, the price looked too good to be true, but this set exceeded my expectations! The quality is amazing, and it fits so nicely. It took about 10 days to arrive from the UK to Singapore, but it was absolutely worth the wait. Love it!
