    Frequently Asked Questions

    How do I know which size to choose? +
    Check our size guide before ordering: measure your natural waist (at its narrowest point) and compare it to our chart. If you're between two sizes, we generally recommend sizing up for extra comfort, especially if it's your first time wearing a waist trainer.
    Is the waist trainer comfortable to wear all day? +
    Yes, as long as it's properly fitted. Our waist trainers feature adjustable hook-and-eye closures and flexible boning that moves with your body without excessive compression. For first time wear, we recommend easing in gradually, starting with a few hours and building up to a full day, to let your body and the fabric adjust.
    Does the waist trainer work with different outfit styles? +
    Yes, that's exactly what it's designed for. Our waist trainers work discreetly under everyday outfits for a smoothing effect, or can be worn as a standalone piece during workouts for extra core support. It adapts to your routine, not the other way around.
    Can I machine wash it? +
    No, we recommend hand washing to preserve the waist trainer's structure. Machine washing can damage the boning and warp the fabric over time, so gentle care ensures a piece that lasts much longer.
    Does the waist trainer suit all body shapes? +
    Yes, our styles feature adjustable closures that adapt to different silhouettes. If you're unsure which fit is most flattering for your shape, feel free to check customer reviews or get in touch with us for personalised advice.
    What if my size doesn't fit? +
    No problem, we offer free exchanges within 30 days of delivery. Simply contact our team at support@lunarune.co and we'll arrange a replacement size.
