How to Choose a Swimsuit That Actually Fits You

Bust, waist, hips and rise — the four measurements that decide whether a swimsuit works, and which cuts suit which shape.

How to Choose a Swimsuit That Actually Fits You

Most swimwear disappointment isn't about the body wearing it — it's about buying a cut that was never going to work, in a size chosen by guesswork. Here's how to get it right the first time.

Measure before you shop

You need four numbers, taken over bare skin with a soft tape:

  • Bust — around the fullest part, tape level at the back.
  • Underbust — directly under the bust, snug but not tight.
  • Waist — the narrowest point, usually just above the navel.
  • Hips — the fullest part, feet together.

Write them down. Swimwear sizing varies far more between brands than regular clothing does, so a number that fits one label tells you very little about the next. Always compare your measurements to the actual size chart.

Match the cut to the shape

If your hips are wider than your bust

Look for a bandeau or a triangle top with detail — ruffles, texture, a bold print — to balance the line. Pair it with a plain, higher-cut bottom. High-leg bottoms lengthen the leg, which visually evens out a fuller hip.

If your bust is wider than your hips

Prioritise support: a top with a proper underwire, thicker straps or a halter neck. A patterned or textured bottom draws the eye down and balances the proportion.

If you want more definition at the waist

A one-piece with side panelling, ruching or a cutout at the waist does this better than any two-piece. High-waisted bikini bottoms achieve a similar effect while still being a two-piece.

If you're long through the torso

One-pieces are the usual problem area — a suit that fits everywhere else will pull uncomfortably at the shoulders. Look for adjustable straps, or go for a two-piece and skip the issue entirely.

The rise matters more than people expect

Bottoms come in roughly three rises, and this single choice changes the look more than the print does:

  1. Cheeky / Brazilian — sits low, minimal back coverage.
  2. Classic — the middle ground, sits on the hip.
  3. High-waisted — sits at or above the navel, covers the midsection.

If you're between two sizes on the bottoms, size up. Swimwear stretches when wet, but a bottom that digs in dry will still dig in wet.

Fabric and lining

Look for a fabric with elastane content — that's what gives recovery, meaning the suit snaps back rather than sagging after a swim. A fully lined front is worth having: it stops the fabric turning translucent in the water, which is the single most common complaint about cheap swimwear.

A good test: stretch the fabric between your hands and hold it up to the light. If you can see through it stretched, you'll see through it wet.

Try the movement test

Before you commit, do four things in the suit: raise both arms overhead, sit down, bend forward, and take a wide step. If anything shifts, gapes or rides up during those, it will do the same at the beach.

Common questions

What size swimsuit should I buy if I am between sizes?
Size up on bottoms and stay true to size on tops. Swimwear fabric stretches when wet but does not gain coverage, so a bottom that digs in while dry will still dig in after a swim. Tops with adjustable straps or a tie-back give you room to fine-tune the fit.
Which swimsuit style is most flattering for wider hips?
A bandeau or detailed triangle top with a plain, high-leg bottom balances the proportion. The detail at the bust draws the eye up, and the higher leg line lengthens the leg, which visually evens out a fuller hip.
How do I stop a swimsuit going see-through when wet?
Choose a fully lined suit and check the fabric before buying: stretch it between your hands and hold it to the light. If you can see through it stretched, it will be translucent when wet. Fabric with a higher elastane content also holds its opacity better.
How should a one-piece fit if I have a long torso?
It should not pull at the shoulders when you raise your arms. If it does, the suit is too short in the body regardless of how it fits at the bust and hips. Look for adjustable straps, or choose a two-piece, which removes torso length from the equation entirely.
