Unbelievable love it

After giving birth, I honestly thought I’d never feel confident in leggings again but this Scallop Set holds my mummy tummy in beautifully! 💖 The quality is amazing, and the sports bra gives strong support even though it’s a one shoulder design. I’ve already ordered another colour before it sells out again!

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.
