    🧵 Fit Notes

    • Asian sizes typically run 1–2 sizes smaller than UK sizing.

    • For a relaxed fit, size up.
    • Measurements are approximate and may vary slightly by fabric and style.

    Fit Tip: Some of our activewear follows Asian sizing (approx. 1–2 sizes smaller than UK). Refer to the GymBum Size Guide for accurate conversions.
