Size Guide

Find your perfect fit with our detailed sizing guide. Every body is beautiful, and we're here to help you find swimwear that makes you feel confident.

How to Measure

Bust

Measure around the fullest part of your bust, keeping the tape parallel to the floor. Keep the tape comfortably loose.

Waist

Measure around your natural waistline, which is typically the narrowest part of your torso, about an inch above your belly button.

Hips

Measure around the fullest part of your hips, keeping the tape parallel to the floor. Stand with your feet together.

Measuring Tip

For the most accurate measurements, use a soft measuring tape and measure over bare skin or lightweight clothing. Don't pull the tape too tight—it should rest comfortably against your body.

Fit Guide & Tips

Finding Your Perfect Fit

Between sizes? We recommend sizing up for tops and going with your preferred fit for bottoms. Our swimwear is designed to be comfortable and flattering.

Larger bust? Consider sizing up in tops for better support and coverage. Many of our styles feature adjustable straps and ties for a customizable fit.

Petite or tall? Our one-pieces have adjustable features, but please note standard torso length is designed for 5'4" to 5'8". Contact us for personalized recommendations.

Coverage Levels

Full Coverage

Maximum support and coverage. Perfect for active beach days and those who prefer more modest styles.

Moderate Coverage

Balanced coverage and style. Our most popular option, offering comfort and confidence for all activities.

Minimal Coverage

Cheeky and stylish. Designed for sunbathing and making a statement. Less coverage in the back.

Care Instructions

To keep your Lume Tide swimwear looking beautiful and lasting longer:

  • Rinse in cold water immediately after each use to remove chlorine, salt, and sunscreen
  • Hand wash with mild detergent, avoid harsh chemicals
  • Never wring or twist—gently squeeze out excess water
  • Lay flat to dry in shade; avoid direct sunlight and heat
  • Do not use washing machines, dryers, or dry cleaning
