The Complete Guide To Your Perfect Swimwear Fit

Finding the perfect swimsuit shouldn't feel as hopeless as chasing sunshine in the UK. Whether you're working with a petite chest or fuller bust, every body deserves that perfect-fit set, because finding swimwear that supports your shape can transform not just how you look, but how you feel when you hit the beach or pool this summer.

We get the struggle - swimwear shopping often brings a mix of excitement and dread. Will it support? Will it flatter? Will it stay put when you dive in the water? The good news: 2025's swimwear trends are embracing body diversity like never before, with designs that are specifically engineered to enhance what you've got.

Summer calls for swimwear that doesn't just look incredible - it needs to feel incredible too. Whether you're planning pool days, beach escapes, or just some swimwear snaps, the secret lies in finding pieces that are expertly crafted for your unique body. Because when your swimwear fits like it was made just for you, confidence becomes your best accessory.

Swimwear For Larger Busts: Where Support Meets Style

For fuller busts, swimwear isn't just about looking good - it's about feeling secure and supported. The key lies in expertly engineered pieces that blend function with serious style credentials.

What to look for:

• Underwired swimwear that works as hard as your favourite bra to keep everything in place

• Wide, adjustable straps that distribute weight evenly and prevent digging

• Full coverage bikini cups with supportive side panels to lift and shape

• Higher necklines like halter neck swimsuits to provide extra security

• Ruching or gathering across the torso that flatters while offering room to move 

Proper sizing is crucial when shopping for supportive swimwear. Unlike regular clothing, swimsuit sizing often requires extra measurements - the band should fit snugly around your ribcage, and the cups should fully contain breast tissue without spillage.

Look for styles with power mesh linings, side boning, and adjustable straps that work together to create comfortable, perfect-fit pieces. When properly cared for, a high-quality, supportive swimsuit is an investment piece that should last several seasons.

Opt for bold prints and vibrant colours that draw the eye upward, or classic block colours that create a sleek, streamlined silhouette. Tankinis offer the perfect balance of coverage and style, while one-piece swimsuits with strategic colour-blocking can sculpt and shape in all the right places.

Swimwear For Smaller Busts: Creating Curves With Confidence

With designers creating stunning swimwear to flatter every frame, embracing your smaller chest on beach days has never been easier. The right pieces will celebrate and enhance what you've got while keeping you comfortable and confident.

Your perfect pieces:

• Push-up padded swimwear and removable inserts that add volume exactly where you want it

• Moulded cups with light padding for more subtle enhancement

• Triangle & bandeau bikinis that create beautiful shape and definition

• Ruffles, frills, and textured fabrics that add visual interest and dimension

• Bright patterns and horizontal stripes that draw attention to your décolletage

• Cut-out details and strappy designs that create stunning focal points

• Halter neck bikinis that create the illusion of curves

The clever and chic design elements in these styles will work to your advantage. Smaller busts benefit from non-wired bikinis that won't overwhelm your frame, while decorative details like ruffles add visual interest exactly where you want it.

Don't shy away from bold prints and bright colours either. Without having larger busts to overwhelm patterns, you can have fun experimenting with this season's vibrant designs. Try a triangle top with adjustable ties - it’ll give the perfect fit while showing off a standout print.

For even more shaping, layer up with a kimono, cover-up, or lightweight shirt that can be tied at the waist. This will create an hourglass silhouette that’ll take you beautifully from beach to beyond.

Swimwear For Taller Women: Elongating Elegance

When you're blessed with height, swimwear should celebrate those gorgeous long lines while ensuring proportions are perfectly balanced. Tall women often face a unique challenge in finding pieces with enough torso length and straps that don't dig in.

Your standout styles:

• High-waisted bikini bottoms that create the illusion of shorter legs and a defined waist

• One-pieces with strategic cut-outs at the waist or sides to give visual breaks and add interest to your long torso

• Bold, large-scale prints that’ll complement your frame without overwhelming your proportions

• Colour-block designs that create horizontal lines and visual interest across your body

• Long-line tankini tops that hit the right point on your torso without riding up

• Wrap-style tops that create a defined waistline and can be adjusted for the perfect fit

• Belted one-pieces that cinch the waist and create that coveted hourglass shape

The key to flattering swimwear for taller women lies in breaking up length while ensuring adequate coverage. Look for longer length swimsuits that have been designed with longer torso measurements and adjustable straps - these allow you to customise the fit for your shoulder width and torso length. Not all swimwear is created equal, and finding the right swimwear for your body will make all the difference.

Try mixing and matching separates to create unique combinations that work for your proportions, and don't shy away from statement accessories like wide-brimmed hats or layered necklaces - these will add visual weight to your upper body.

Swimwear For Petite Women: Maximising Your Frame

Petite figures deserve swimwear that enhances every inch, creating the illusion of length while maintaining perfect proportions. The goal isn't to make you look taller - it's about creating balance and ensuring every piece works harmoniously with your natural frame.

Your perfect picks:

• High-cut styles that elongate the leg for a more statuesque silhouette

• Vertical stripes and patterns that draw the eye up and down

• Minimal coverage bikini bottoms, like Brazilian or cheeky cuts, that show more leg and create the illusion of height

• Crop-style bikini tops that create a defined waistline and break up your torso

• Monochromatic colours that create one unbroken line from head to toe

• Plunge swimsuits that create a vertical line and draw attention upward

The secret to stunning swimwear for petite frames lies in strategic placement and scale. Choose prints that are proportionate to your frame - delicate florals, small geometric patterns, or fine stripes work beautifully. Avoid overwhelming your figure with oversized prints or excessive detailing that can make you appear smaller. Instead, opt for clean lines and strategic design elements that maximise your natural proportions.

Petite women need pieces designed with shorter torsos, narrower shoulders, and different proportions in mind. Look for petite-specific sizing or adjustable features that allow you to customise the fit. Tie-sides, adjustable straps, and removable padding give you control over how the piece sits on your unique frame.

Last but not least, create visual interest with strategic details - for example, a bold belt at the waist, statement earrings that draw the eye up, or a flowing cover-up that adds movement without overwhelming your frame. Layer delicate jewellery to create vertical lines, and choose cover-ups that hit at the most flattering points - just above or below the knee for sarongs, or cropped styles that show your waistline.

The petite advantage? Your compact frame means you can pull off trends that might overwhelm taller figures - think cut-out details, intricate strappy backs, and bold colour combinations that create stunning focal points. Embrace your proportions and choose pieces that celebrate your petite powerhouse energy.

Maximum Coverage: Confidence In Every Style

Sometimes more coverage means more confidence, and there are plenty of options that can cover you up while keeping you looking chic. Whether you prefer modest styling, you're seeking sun protection, you want to minimise certain areas, or simply feel most comfortable with more coverage, the modern swimwear landscape offers stunning pieces that never compromise on style.

Your confidence-boosting options:

• Long-sleeve rash guards that provide sun protection and arm coverage

• High-neck swimsuits that offer elegant coverage without sacrificing style

• Zip-front styles for adjusting your coverage level throughout the day

• Swimdresses and swim skirts that offer extra coverage around the hips and thighs

• Tankini sets that provide the versatility of a two-piece with the coverage of a one-piece

• Boy-short bikini bottoms that offer more coverage while remaining incredibly flattering

• High-waisted vintage-inspired styles that offer tummy coverage while creating a timeless silhouette

Full coverage doesn't mean sacrificing personality. Choose pieces with interesting necklines, strategic cut-outs for glimpses of skin, or bold prints that make a statement. Complement your covered-up style by layering it with delicate jewellery, adding a wide-brimmed hat, choosing statement sunglasses, or sarong-style wraps that can be adjusted for your perfect level of coverage.

This style often provides the most comfortable swimwear experience. Without worrying about straps slipping, coverage shifting, or constant readjustment, you're free to dive into every activity with complete confidence. Look for pieces with flat-seam construction, quick-dry fabrics, and four-way stretch that moves with your body.

Many coverage swimwear options now incorporate UPF ratings so they work double time - they protect your skin while keeping you looking incredible. Fabrics with UPF 50+ block 98% of harmful UV rays, making them perfect for extended beach days or active water sports.

How Do You Find The One?

Finding your perfect swimsuit doesn't have to be a frustrating experience. With the right approach, you can discover flattering options that fit beautifully and stay in place.

Start with accurate measurements. Take your current bust, waist, and hip measurements before shopping. Your body changes over time, so don't rely on old measurements. Wear minimal clothing for accuracy, and consider having a friend to help.

Consult size charts carefully. Each brand uses different sizing standards. Always check the specific brand's size chart rather than assuming your usual size will fit. When between sizes, consider your body type - size up for fuller busts, and down for smaller busts if support is less critical.

Try multiple sizes. Never settle for the first swimsuit you try on. Grab the same style in two or three sizes to compare fit. The right size should feel secure without digging in or creating spillage.

Movement-test every suit. A swimsuit might look great when standing still, but it could fail in action. Before buying, try it on and…

• Raise your arms overhead

• Bend forward at the waist

• Sit down and cross your legs

• Twist your torso side to side

If anything shifts, gaps, or feels uncomfortable during these movements, try a different size or style.

Remember that finding the right swimsuit might mean trying several options. Be patient with the process, and prioritise comfort and security over following trends that don't work for your unique body.

How To Care For Your Swimwear

You did it, you found ‘the one’! But, to avoid heartbreak, you need to take care of your swimwear so it’ll last.

• Immediately after use, hand wash it in cold water with mild soap

• Avoid harsh wringing - gently press water out with a towel instead

• Air dry flat or hang it away from direct sunlight to prevent fading

• Always rinse thoroughly after swimming in pools or ocean water to remove chlorine and salt

• Store in a cool, dry place without folding to maintain elasticity

• Rotate between multiple swimsuits during holidays to extend their lifespan

• Replace your swimwear when elasticity diminishes

Remember that proper care of swimwear extends its life and your confidence when wearing it.
