How to Choose a Swimsuit for Your Body Type

Choose a swimsuit by what you want it to do, not by a label for your body. Decide how much coverage you want, how much support you need and where you want the fabric to sit. Then try it on, move in it and keep the one you forget you are wearing.

Start with what you want, not what to hide

Most swimsuit advice starts by sorting bodies into shapes and telling you what to hide. That advice makes buying harder and the beach less fun.

A better question is what you want the swimsuit to do. Do you want more coverage or less? Do you need support, or do you want freedom? Do you want to swim hard, or lie on a towel? Answer those and the choice narrows fast.

AOBA designs and fit-tests its swimwear on Indian bodies, in sizes S to XL. The advice below works with that range.

Pick the swimsuit you will forget you are wearing.

Test the fit before you commit

Do this at home when your order arrives, and use the 7-day returns if the fit is off.

  1. Stand and raise your arms

    Nothing should shift, pinch or slip. If the top rides up, it is too small or the cut is wrong for you.

  2. Sit and bend forward

    Check the fit at the hips and bust. A swimsuit should stay put when you move.

  3. Walk across the room

    Notice any strap or edge that digs in. Comfort on a short walk predicts comfort over a whole day.

  4. Wet the fabric if you can

    Swim fabric changes when wet. If it still feels secure, you have the right size.

Three fit questions people ask

I sit between two sizes. Which one?

Go up if you want ease or have a long torso, and down if you want a snug, secure hold. Use the size help on AOBA for a recommendation based on bust, waist and hip.

Do I need a skirt to feel covered?

No. A skirt adds coverage over the hips and thighs, but plenty of people feel secure in a plain monokini or a bikini set. Choose what feels good.

Can I mix sizes in a bikini?

Some stores sell tops and bottoms separately. Check each AOBA product page for how the set is sold.

Common questions

How do I choose a swimsuit for my body type?

Choose by fit goal. Decide how much coverage and support you want, try styles that deliver it, and keep the one that stays put when you move.

What swimsuit gives the most coverage?

A monokini with a skirt covers the middle and hips. See AOBA monokinis.

What is easiest to adjust?

Triangle and halter bikini tops with ties can be tightened or loosened. See AOBA bikini sets.

Should I buy a swimsuit a size up?

Buy your size and check the fit note. Swim fabric stretches, and a suit that is too big will let in water and shift.

What is the return policy?

AOBA offers easy 7-day returns. Read the full conditions on the refund policy page before you order.
