How to Take Your Measurements

For best results with the Fearless size guide, use a soft tape and keep it straight and level even around your body.

  • Bust

    Measure around the fullest part of your bust (nipple height), keeping the tape level across your back and chest.

  • Waist

    Stand relaxed, arms down, and place the tape comfortably around your waist without pulling firm.

  • Hips

    Place tape around your hips, ensuring it runs across your bum. The tape should sit smoothly against your body without digging in.

  • Torso

    Measure from the centre of your shoulder down to the inner seam of your underwear. Hold the tape firmly without slack.

    Note: If your torso measures over 76cm or you’re taller than 170cm, you likely have a long torso.

Frequently Asked Questions

How do I find my size in Fearless Swimwear?

To find your size in Fearless Swimwear, measure your bust and hips using a soft tape measure kept straight and level around your body. Measure around the fullest part of your bust at nipple height, and around the fullest part of your hips across your bum. Match your measurements to the Fearless size guide. If your bust and hips fall into different sizes, Magic Sizing™ allows you to choose a different size for your top and bottom in a one piece.

How do I measure myself for swimwear?

For best results, use a soft tape measure and keep it straight and level around your body. For your bust, measure around the fullest part at nipple height, keeping the tape level across your back and chest. For your waist, stand relaxed with arms down and place the tape comfortably around your waist without pulling firm. For your hips, place the tape around the fullest part of your hips ensuring it runs across your bum, sitting smoothly without digging in. For your torso, measure from the centre of your shoulder down to the inner seam of your underwear without slack.

How should Fearless Swimwear fit?

Fearless Swimwear is designed to feel compressive but never uncomfortable. When you first put it on, it should require a little bit of a jig to pull up - this is normal and means the fabric is doing its job. Once on, it should feel firm and supportive without digging in, rolling or riding up. The 360 degree power mesh compression is designed to cinch the waist and smooth the body while still allowing full movement and comfort throughout the day.

What is Magic Sizing™ and how does it work?

Magic Sizing™ is Fearless Swimwear's mix-and-match sizing system for one piece swimsuits. Instead of choosing one size for the whole garment, you select your bust size and your hip size independently. This means if you are a size 12 on top and a size 16 on the bottom, you can order exactly that combination rather than compromising on fit. Magic Sizing™ is designed for women whose bust and hip measurements fall into different standard sizes, which is extremely common.

What size should I choose if I have a larger bust?

If you have a larger bust, measure around the fullest part of your bust at nipple height and use that measurement to select your top size. Fearless Swimwear offers dedicated styles with serious bust support for larger cup sizes. If your bust and hips fall into different sizes, Magic Sizing™ allows you to choose your bust size for the top and your hip size for the bottom of a one piece, so both fit correctly without compromising on support or coverage.

What size should I choose if I have wider hips?

If you have wider hips, measure around the fullest part of your hips ensuring the tape runs across your bum. Use that measurement to select your bottom size. If your hips and bust fall into different sizes, Magic Sizing™ allows you to choose a different size for the top and bottom of a one piece swimsuit so you get the right fit across your whole body rather than sizing up or down overall.

How do I know if I have a long torso?

You likely have a long torso if your torso measurement is over 76cm or if you are taller than 170cm. To measure your torso, place a tape at the centre of your shoulder and measure down to the inner seam of your underwear, holding the tape firmly without slack. If you have a long torso, Fearless has a dedicated long torso collection designed with extra length through the body so the swimsuit sits correctly without pulling at the shoulders or riding up at the crotch.

Does Fearless Swimwear cater for larger cup sizes?

Yes. Fearless Swimwear has a dedicated range of bikinis and one pieces designed with serious bust support for larger cup sizes. Many styles feature inbuilt support structures that offer lift and security without bulky padding or uncomfortable underwires. Magic Sizing™ also allows you to choose a larger size for your bust and a smaller size for your hips in a one piece, so the top fits your cup size without excess fabric through the bottom.

What if I am between sizes in Fearless Swimwear?

If you fall between sizes, Fearless recommends sizing up for more comfort or sizing down for a firmer, more compressive fit. Fearless Swimwear is designed to be compressive but never uncomfortable - the fabric has stretch and recovery built in. If you are unsure, you can take the Fearless fit quiz for a more personalised recommendation, or email fit specialist Emma who has over a decade of professional bra fitting experience and specialises in supportive swimwear and accurate cup sizing.
