The Best Functional Swimwear That Still Looks Fabulous

Few things ruin a beach or pool day faster than a shifting bikini top or bottoms that won't stay put.

Whether you’re chasing after kids or heading to the pool bar for another marg, functional and  fabulous swimwear for women is your best bet for reliable support without sacrificing any style. 

Sure, some fashion-forward swimwear prioritises looks over practicality, but there is a sweet spot where style and function meet.

At Maison SL, we understand that looking elegant shouldn’t mean compromising on comfort. If you're tired of swimsuits that only work for sunbathing, here’s your guide to finding swimwear that stays put and still makes you feel fabulous.

What Makes Swimwear Functional?

When we say functional swimwear that is still stylish, we mean pieces that are designed to support you, not just look good while you’re still.  

A recent Reddit thread among women over 30 highlighted the frustration many feel about flimsy, fashion-only suits. But not every swimsuit is built in this style. There are plenty of supportive styles that are just as chic.

Key features you’ll want include:

• Bust support. This is especially vital for ladies with fuller cups

• Secure fit. A good fit ensures no more accidental wardrobe malfunctions.

• Freedom of movement. Non-restrictive swimwears means you can actually enjoy swimming or beach sports.

While shopping for stylish swimsuits with support, you should look for clever construction details like wide, adjustable straps, underwired cups, full lining, and hook-and-eye closures instead of flimsy ties. 

Similarly, high-quality elastic and firm-fitting fabrics ensure your swimwear holds its shape all day.

Functional Swimwear Styles That Still Look Sophisticated

From supportive one-pieces to underwired bikini cups, these are some categories and recommendations you’ll want to consider. 

1. Supportive One-Pieces

A one-piece swimsuit can be elegant, flattering, and, most importantly, incredibly secure.

For extra support, look for designs that offer built-in bras or internal shelf support, which help hold everything in place without compromising on comfort. 

For example, the Gottex Lattice V Neck Surplice Onepiece Swimsuit has soft built-in bra cups, tummy control, and adjustable straps to keep you feeling secure while looking fantastic.

You may also want to seek out styles with shaping panels or tummy control fabric if you want a gently sculpted look that still feels comfortable all day. 

The Empreinte Mood One Piece Plunge Swimsuit offers a shaping and smoothing effect, thanks to the original Mayfair fabric with Lycra Beauty fibres.

2. Sporty-Chic Swimwear

For those who prefer full flexibility with zero fuss, sporty-chic styles are the perfect solution. 

These pieces are ideal if you plan to swim laps, paddleboard, or simply run around the beach with children. They combine practicality with a sharp, modern style that doesn’t sacrifice an ounce of style.

The &Pomona Tropical Tank 1 Piece Swimsuit has a high-cut tank-top style. Not only does this flatter your figure, but it keeps your bust covered no matter how many laps you swim. The swimsuit is also fully lined for extra protection.

The Banana Moon Hakko Sprint Tank Bikini Set is another sporty option, as the bikini top features a sports bra-like cut. This extra support, paired with the central zip fastening, means you’ll be feeling invincible and looking fine when someone brings out the frisbee. 

3. Bikinis & Briefs With Extra Support

 Think bikinis offer less support than bras? Think again.

With the right fit and style, they can offer just as much support and coverage as a one-piece. Underwired or moulded cups will help to support the bust and maintain shape, while bra-like clasp fastenings offer a more secure hold than traditional string ties.

The Maryan Mehlhorn Serpent Wired Bikini Set is an unparalleled example of support and fashion-forward style. The bikini has an intricate snake print with a contemporary balcony bra style. Plus, you can trust the adjustable straps, underwire, and back clasp to stay put.

If you’re looking for more support around your middle or bottom, a high-waisted bikini will tick both the functionality and style boxes.

The Lise Charmel Antigel Chiquissima High Waisted Bikini Briefs are a fabulous option for this purpose. They come in navy or pink, and provide full coverage whilst flattering your figure and allowing a full range of movement. Perfect.
