How to Choose a Flattering One Piece Swimsuit - The Ultimate Guide

Finding the perfect one piece swimsuit can feel surprisingly difficult.

Some pinch in the wrong places. Some flatten your shape. Others look beautiful on the hanger but leave you feeling uncomfortable the moment you step onto the beach.

The truth is, a flattering one piece swimsuit isn't about changing your body. It's about finding a swimsuit designed to work with your body.

At Ocean Soul Swimwear, we've spent years fitting women of all shapes, sizes, ages and lifestyles. From surfers and freedivers to mums chasing children along the beach, we've learnt that the most flattering swimsuit isn't necessarily the trendiest one. It's the one that makes you feel confident, comfortable and supported.

Whether you're shopping for your next Bali holiday, searching for a swimsuit that stays on in the surf, or simply wanting to feel amazing at the beach, this guide will help you choose the perfect one piece swimsuit.

What Makes a One Piece Swimsuit Flattering?

Many women assume flattering swimwear is all about coverage.

In reality, it's about proportion.

The best one piece swimsuits create balance throughout the body. They highlight your favourite features while providing support where you want it most.

Key elements that make a swimsuit flattering include:

Strategic panelling
Waist definition
Quality fabric with gentle compression
Necklines that suit your shape
The right leg cut
Proper bust support
A secure fit that stays in place

When these elements come together, the result isn't just a swimsuit that looks good. It's one that changes how you feel when you wear it.

Look for Waist Definition

One of the biggest mistakes swimwear brands make is creating swimsuits that are simply tubes of fabric.

Without shape through the waist, many swimsuits can make the body appear boxy, regardless of your natural figure.

This is why panelled designs have become so popular.

Our bestselling Sulawesi and Mentawai one pieces feature carefully placed contour panels that visually create shape through the waist while elongating the body.

Rather than squeezing or compressing aggressively, the design works with your natural silhouette.

The result is a swimsuit that feels supportive while still looking effortless.

Choose Fabric That Supports Rather Than Restricts

Fabric is one of the most overlooked parts of swimwear shopping.

A beautiful cut can only do so much if the fabric lacks quality.

Low-quality fabrics tend to stretch out quickly, lose their shape and become transparent when wet. They often provide little support and can cling in unflattering ways.

High-quality swimwear fabrics should:

Hold their shape over time
Offer gentle compression
Feel soft against the skin
Resist chlorine and saltwater
Move comfortably with the body

At Ocean Soul Swimwear, we use premium Italian recycled fabric that provides subtle support while remaining incredibly comfortable.

The goal isn't to squeeze you into a shape. It's to enhance the shape you already have.

Find the Right Neckline

The neckline of a swimsuit can dramatically change how it looks on your body.

If you have a fuller bust, adjustable zip-front styles can offer flexibility and support.

Women with smaller busts often suit higher necklines, square necklines, or zip-front styles that create structure through the upper body.

Our Sulawesi one piece features an adjustable front zip, allowing you to customise the neckline depending on your preference and activity level.

A slightly open zip can create a longer neckline, while a higher zip provides more coverage and support.

Don't Be Afraid of a Higher Leg Cut

Many women assume a lower-cut leg will be more flattering.

Surprisingly, the opposite is often true.

A moderate to higher-cut leg can create the illusion of longer legs and a more elongated silhouette.

The key is balance.

An overly high-cut leg may feel uncomfortable for some women, while a very low cut can shorten the appearance of the legs.

Our one pieces are designed with carefully balanced leg lines that provide comfort, coverage and elongation all at once.

Think About How You'll Actually Use It

A flattering swimsuit isn't just about appearance.

It's also about confidence.

And confidence often comes from functionality.

Ask yourself:

Will you be surfing?
Swimming laps?
Snorkelling?
Relaxing by the pool?
Chasing children on the beach?
Travelling through Bali and Indonesia?

The more active your lifestyle, the more important support and security become.

Many women discover that they feel more confident in a swimsuit that stays exactly where it should than in one that's constantly shifting.

This is one reason why long sleeve swimsuits have become increasingly popular.

They offer:

Additional sun protection
Greater support
More security during movement
Less need for sunscreen

And importantly, they look incredibly elegant.
