The right one piece swimsuit changes everything. It is the difference between adjusting your straps mid-lap and forgetting you are wearing a suit at all. This guide covers everything you need to know to find the one that’s right for you.
A one piece swimsuit is one of the most versatile pieces of clothing you can own. It takes you from early morning pool sessions to ocean swims, beach days and everything in between. But not all one pieces are created equal. With so many styles, back designs and fabric choices available, knowing where to start can feel overwhelming.
Whether you are a competitive swimmer, an ocean enthusiast or someone who simply wants a suit that stays put, this guide will help you find the one piece swimsuit that is made for the way you move.
The Most Important Thing: Back Style
The back of your one piece swimsuit determines almost everything: how secure it feels, how much movement you have and how well it stays in place during activity. There are two main back styles to understand:
Fixed-Back One Pieces
A fixed-back swimsuit has non-adjustable straps that are sewn into position. This creates a consistently secure fit that does not shift, twist or need readjusting during your swim. Fixed-back styles are ideal for active swimmers, surf athletes and anyone who wants a suit that stays exactly where it is meant to be.
JAYD Swimwear fixed-back styles include the Lennox, Albi, Zambia, Finley, Apsley, Airlie, Siena, Soraya, Zimmy and Tallow; each offering a slightly different silhouette and coverage level.
Tie-Back One Pieces
A tie-back swimsuit features adjustable straps that can be loosened, tightened or tied in different ways to customise the fit and coverage. Tie-back styles offer more flexibility and are a popular choice for those who want to adjust their silhouette or who fall between sizes.
JAYD Swimwear tie-back styles include the Isla and Riva, both designed to be as flattering tied up as they are worn relaxed.
Understanding Coverage
Coverage refers to how much of your body the swimsuit covers, specifically your booty. At JAYD Swimwear we offer three coverage levels so you can find exactly what feels right for you.
Cheeky Coverage
Cheeky coverage sits higher on the hip and lower on the seat, creating a more open and elongating silhouette. Popular for beach days, poolside lounging and lifestyle wear.
Mid Coverage
Mid coverage offers a balanced silhouette, our JAYD mid coverage pieces sit across the cheek, making them versatile enough for both active and lifestyle wear.
Full Coverage
Full coverage provides complete cheek coverage for maximum comfort and confidence. Ideal for training, surf life saving and anyone who prioritises security over style. JAYD full coverage pieces offer more material and a scoop look around the cheeks.
Fabric Makes the Difference
The fabric of your one piece swimsuit determines how long it lasts, how it performs in the water and how it feels against your skin. At JAYD Swimwear every suit is made from premium Italian eco fabric paired with a 100% PBT lining, both chosen for their chlorine resistance, shape retention and long-term durability.
This means your JAYD one piece will hold its colour, its shape and its support session after session, whether you are training in a chlorinated pool or swimming in the ocean.
How to Find Your Size
Swimwear sizing can vary significantly between brands. At JAYD Swimwear we recommend checking our size and style guide before ordering, particularly if you are between sizes (if you are between sizes, we recommend sizing up) or new to the brand. Performance swimwear is designed to feel slightly more compressive than fashion swimwear, which is intentional. It is what keeps the suit in place during movement.
Choosing the Right One Piece for Your Activity
Different activities call for different design priorities. Here is a quick guide to help you match your suit to your swim:
- Pool training and squad swimming: Prioritise a fixed-back, full or mid coverage swimsuit with chlorine resistant fabric. The Lennox, Finley and Apsley are strong choices.
- Ocean swimming and surf life saving: Look for a fixed-back style that stays secure in waves and current. The Zambia, Airlie and Albi perform exceptionally well in open-water conditions.
- Beach and lifestyle: Tie-back styles or cheeky coverage one pieces offer the most flattering silhouette for relaxed wear. The Levanto, Isla and Riva are designed with this in mind.
- Triathlon and open-water racing: A streamlined fixed-back with mid-coverage and minimal drag is ideal. The Siena was designed with performance in mind.
Final Thoughts
The perfect one piece swimsuit is out there, and finding it comes down to understanding your back style preference, coverage level, activity and fabric needs. At JAYD Swimwear every one piece is designed to work as hard as you do, in any body of water you choose.
Frequently Asked Questions
What is the best one piece swimsuit for lap swimming?
For lap swimming, look for a fixed-back one piece with chlorine resistant fabric. A fixed-back design stays secure during flip turns and push offs, while chlorine-resistant fabric maintains its shape and colour through repeated pool sessions. JAYD Swimwear's Lennox, Finley and Apsley are all excellent choices for regular pool training.
What is the difference between a fixed-back and tie-back swimsuit?
A fixed-back swimsuit has set, non-adjustable straps that provide consistent security during movement. A tie-back swimsuit has adjustable straps that can be customised for fit and coverage. Fixed-back styles are generally preferred for active swimming, while tie-back styles offer more flexibility for lifestyle and beach wear.
How should a one piece swimsuit fit?
A well-fitting one piece swimsuit should feel snug and supportive without restricting breathing or movement. The straps should sit firmly on the shoulders without digging in, and the fabric should feel comfortably compressive. There should be no gaping at the chest or excess fabric at the seat. Performance swimwear is designed to feel slightly more fitted than fashion swimwear, this is intentional and ensures the suit stays in place during activity.
Is a one piece swimsuit good for ocean swimming?
Yes, a one piece swimsuit is an excellent choice for ocean swimming. It provides more coverage and security than separates, reduces the risk of the suit shifting in waves and surf, and typically offers better UV protection. For ocean swimming, look for a fixed-back style with secure straps and a chlorine and saltwater resistant fabric.
How to Care for Your One Piece
Rinse your one piece in cold fresh water immediately after every swim to remove chlorine, salt and sunscreen. Hand wash gently with a mild detergent and lay flat to dry in the shade. Avoid wringing, tumble drying or leaving your suit in direct sunlight for extended periods. Proper care significantly extends the life of any swimsuit.
