What to Wear Under Swimsuit

Welcome to our guide on "What To Wear Under Swimsuit." In this article, we explore the age-old question of whether it's necessary to wear anything under your swimsuit.

From discussing the importance of bathing suit support features to identifying how to tell if a swimsuit has underwear-like designs, we've got you covered.

Plus, we'll provide you with a handy swimsuit checklist to ensure you find the perfect fit for your beach adventures.

Whether you're wondering about fabric choices, where to buy swimming costume for women, or “What size swimsuit should I buy?” we've got all the answers you need to make a splash, at Simply Beach.

What this article covers:

Should You Wear Anything Under Your Swimsuit?

When it comes to wearing anything under your swimsuit, it's entirely up to you. Swimsuits are crafted to be worn solo, providing you with the freedom and flexibility to enjoy your time in the water without additional layers.

At Simply Beach, we understand the importance of feeling confident and comfortable in your beachwear. That's why our focus is on providing high-quality swimsuits that meet your needs without requiring additional layers.

Whether you prefer the sleek simplicity of a one-piece or the versatility of a bikini, our carefully curated collection offers options that prioritise both style and functionality.

Would You Recommend Wearing a Standard Bra Under a Bathing Suit?

We wouldn't recommend wearing a standard bra under your bathing suit. Standard bras aren't engineered to handle the challenges posed by water.

When they get wet, they become uncomfortable and cumbersome, weighing you down rather than offering the lift you need to enjoy your beach activities to the fullest.

At Simply Beach, we recommend opting for a swimsuit that comes equipped with built-in support features.

After trying out this product, our Desert Sunset Moulded Underwired Swimsuit from Charmline, for example, contains moulded underwire cups and tummy control.

Whether it's moulded cups, under wire, or adjustable straps, these elements specifically aim to provide the comfort and security you need for a day of fun in the sun.

What If I Need A Bra For Under My Bathing Suit?

In our experience, many swimsuit designs on the market today feature integrated cups or an underwire to provide added lift and security where you need it most.

These ingenious designs combine the best of both worlds, offering the security of a bra with the sleekness of a swimsuit.

Consider our Ceylan Underwired Crossover Swimsuit from Roidal. Our team discovered through using this product that its crossover style with underwire and adjustable straps provides extra support.

Whether you prefer a beautiful one-piece swimsuit or a trendy bikini, Simply Beach offers all the crucial features like adjustable straps and moulded cups. This allows for a customised fit that flatters your figure and enhances your comfort.

What Other Forms of Bathing Suit Support Are There?

Besides a swimming costume with a built-in bra, there are several other options to consider for extra support.

  1. Under Wire, Padding Or Boning: Swimsuit tops with these additional features are excellent choices for those seeking added stability and lift. Swimsuit designs strategically incorporate these supportive elements to enhance your natural shape and provide a secure fit.
  2. Tankinis And One-Piece Swimsuits: Tankinis offer the convenience of a two-piece ensemble while providing the coverage of a one-piece, making them versatile and flattering for various body types. Similarly, one-piece swimsuits often contain supportive elements like tummy control panels, and reinforced bust cups, offering maximum coverage.

Now, you can feel confident and comfortable wherever you are - whether you're lounging by the pool or catching waves at the beach.

How to Tell If a Swimsuit Has Underwear-Like Features

As per our expertise, to determine if a swimsuit has underwear-like features, we recommend investing in structured cups or padding that offer support akin to lingerie. 

These elements suggest that the swimsuit is engineered for extra comfort, ensuring you feel secure and confident during your beach outings.

At Simply Beach, we meticulously focus on the small details, ensuring our swimwear collection offers you the best possible fit and feel for your aquatic adventures.

Swimsuit Support Checklist – A Few Things to Remember

When selecting your perfect swimsuit, keep these key points in mind for optimal wear:

  • Opt for swimsuits with built-in bra support.
  • Look for additions like adjustable straps and moulded cups like the Pink Aqua Moulded Swimsuit from Charmline, which allow for a customised fit that flatters your figure.
  • Consider swimsuit styles with underwire, padding, or boning for extra support. After conducting extensive research, we discovered that this is particularly helpful if you have larger bust sizes or prefer additional stability.
  • Pay attention to details like structured cups and clipback closures, as they indicate underwear-like aspects that provide enhanced fit.
  • Choose a swimsuit that makes you feel confident and fabulous, allowing you to fully embrace the beach life with style and grace.

At Simply Beach, we're committed to helping you find the ideal swimsuit that not only makes you look gorgeous but also comfortable during all your oceanic adventures.


In deciding what to wear under your swimsuit, the key is to prioritise comfort, support, and confidence.

While some people may opt for additional layers or lingerie-like features, many quality swimsuits come equipped with built-in underwires, etc to ensure you feel secure and stylish in and out of the water.
