A figure-shaping one-piece swimsuit – how the design of the swimsuit shapes the silhouette

Shaping does not mean compressing or altering the body’s proportions. A shaping swimsuit works through the continuity of its form, the direction of its lines, the elasticity of the fabric and its stable fit. In KORNELIA RATAJ’s one-piece designs, a smooth front, a simple neckline, adjustable thin straps and a higher cut at the hips create a minimalist composition without excessive embellishments. Double-layered construction, concealed seams and a heat-transfer label enhance comfort and ensure an aesthetic finish. The final visual effect is influenced by:

  • a simple neckline that gives the top half of the swimsuit a neat look and shows off the shoulders without being too low-cut;
  • adjustable straps, allowing you to better adjust the length of the top to suit your height, bust size and torso;
  • a higher cut at the hips, which makes the legs look longer and emphasises the figure’s proportions;
  • a smooth, two-layer formulation that ensures even coverage.

A figure-shaping swimsuit helps to define the body’s contours, but is not directly responsible for providing support. This is the result of the overall cut, whilst bust support depends mainly on the construction of the top, the tension of the fabric and the adjustment of the straps. The visual proportions of the figure, on the other hand, are influenced by elements such as the shape of the neckline, the definition of the waist, the depth of the cut around the thighs and the colour. A well-chosen figure-shaping swimsuit combines these features in a way that suits how you intend to wear it.

Ruffles, contrasting panels and decorative stitching may catch the eye, but they are not essential to achieving a cohesive and orderly design. In current designs, figure-flattering swimwear is based on simplicity: clean lines, a solid colour and a precise fit play the leading role. As a result, a one-piece shaping swimsuit remains minimalist and is not dictated by any single seasonal trend. Slimming one-piece swimsuits It is worth viewing this as a subtle visual effect resulting from the design and colour, which emphasises the body’s natural proportions.

Figure-shaping swimsuit – tailored to the bust, waist, hips and torso length

Even the best-designed figure-flattering swimwear won’t look good if you choose the wrong size. A well-fitting swimsuit should hug the body closely, and the compression of the fabric – which can be felt when dry – is a natural feature of the garment. However, a size that is too small can cause the fabric to be too tight, reduce comfort, diminish coverage and lead to the edges rolling up. Conversely, a swimsuit that is too loose may become baggy when wet, slip out of place and provide less support, as the fabric becomes slightly more elastic when wet. Before purchasing, therefore, compare your bust, waist and hip measurements with the size chart and take your torso length into account. When selecting online, familiarise yourself with the product description, photos and fitting guidelines:

  • pay attention to how the straps are positioned and whether they can be adjusted;
  • take a look at the extent of the incision in the thigh area;
  • Choose a style that suits your preferred level of coverage for your bottom and the activity you’re planning.

This one-piece shaping swimsuit with adjustable straps allows you to precisely adjust the fit of the top to suit your bust size; however, comfort also depends on your underbust measurement, torso length and the level of support you require. The design of this shapewear swimsuit ensures a natural fit on the figure. We believe that the waist, tummy and hips do not require correction, but rather a conscious adaptation of the cut to your own needs. Among the available bottoms, you’ll find both higher-cut and fuller-cut options, allowing you to choose the level of coverage and freedom that suits your own style and comfort.

Shapewear swimwear should be comfortable whether you’re walking, swimming or relaxing. A well-fitting women’s figure-shaping swimsuit doesn’t need constant adjusting.

Shapewear swimsuits – one-piece or a mix-and-match set – choose the option that’s right for you

In the swimwear category, we present one-piece shapewear swimsuits and bottoms that can be paired with a separately chosen top. A one-piece figure-hugging swimsuit creates a continuous line from the neckline to the hips, whilst the high-cut bottoms allow you to adjust the size and fit of the top independently. Compare the key differences:

  • The one-piece design creates a seamless surface and allows the torso to be covered;
  • The high-cut design allows you to adjust the level of coverage over the stomach and bottom independently of the top;
  • a more high-cut leg line reveals more of the hips, whilst a fuller cut creates a more understated, classic silhouette;
  • Separately selected pieces make it easier to choose two different sizes when the upper and lower body have different proportions.

Shapewear one-piece swimsuits are ideal for swimming, walking and relaxing when you want a one-piece design. Shapewear two-piece swimsuits, on the other hand, offer greater freedom to mix and match a top with high-cut bottoms.

The most important factors remain comfort, waist stability and freedom of movement, both when dry and when wet.

Figure-flattering swimwear – fabric, craftsmanship, colour, fashionable design, comfort and elegance

Shapewear swimwear stretches during movement and comes into contact with water, chlorine, salt and cosmetics. Its premium quality is therefore evident in the choice of fabric, the evenness of the finishes, the stitching and the durability of the details. The KORNELIA RATAJ collection of shaping swimwear uses ECONYL® Lycra made from recycled fibres, and the swimsuits are constructed with a double-layer design. The fabric is resistant to chlorine, pilling, oils and creams, and is OEKO-TEX® Standard 100 certified. To ensure your swimsuit retains its shape and appearance for longer:

  • After bathing, rinse it in cool or lukewarm, clean water;
  • Hand wash or machine wash on a gentle cycle at the temperature indicated on the label, with similar colours;
  • do not bleach and do not use harsh detergents;
  • Do not tumble dry or dry directly on a hot radiator;
  • Allow the outfit to dry completely before putting it away.

A figure-shaping swimsuit works primarily thanks to its carefully designed cut, which emphasises your natural curves and supports your figure. Stitching, cut lines and ruffles can make your waist look slimmer or your legs look longer. A swimsuit like this doesn’t change who you are – it simply accentuates what makes you unique. It’s the perfect solution for women who want to feel comfortable and confident, without compromising on style.

Asymmetrical designs, such as a single strap, are also appearing, whilst minimalist lines remain a timeless choice.

It’s worth giving careful thought to your choice of swimwear, especially if you’re looking for a figure-flattering effect. The most important things are a good fit and a stretchy fabric that ensures comfort and freedom of movement. Also pay attention to details such as cut-outs or stitching, which affect both the look and comfort.


Shapewear swimwear helps to emphasise your figure and ensures comfort by the water. At the KORNELIA RATAJ online shop, you’ll find carefully designed styles with refined cuts and high-quality fabrics that combine style with functionality.


The term „shaping” alone does not automatically imply strong support, as this depends on the design of the bust section, the band size and the way the straps are positioned. A well-fitting bra should stay in place whilst you move, and the neckline must neither gape nor feel too tight.


Make sure the fabric fits snugly under the bust, that the straps are adjustable, and that the neckline provides the desired level of coverage. If your bust, waist and hip measurements indicate different sizes, it is worth providing the shop staff with your exact measurements, as well as your height and torso length, before making a purchase.


Underwiring is not essential, as its primary function is to give the bust area a specific shape, rather than to shape the entire figure. Stability can also be provided by a well-fitting cut, the elasticity of the fabric, the correct band size and adjustable straps.


Measure your bust, waist and hips, and for a one-piece swimsuit, take your height into account as well. A swimsuit that’s too small may pull at the shoulders and dig in at the edges, whilst one that’s too big will gape, wrinkle or slip out of place when wet.


A V-neck draws the eye vertically and can subtly emphasise the natural proportions of the figure. A straight neckline creates a calm, clean line across the shoulders, so it’s worth choosing a style that feels comfortable, suits your preferences and provides support for your bust.


After contact with chlorine, salt or sun cream, rinse your swimwear in clean, cool or lukewarm water and wash it according to the instructions on the care label. Do not wring out the fabric, do not leave the wet swimwear in a bag, and allow it to air dry naturally, away from tumble dryers and direct sources of heat.
