A Guide to Custom Tankini Swimwear

A tankini top combines the convenience of a two-piece swimsuit with the coverage of a longer swimwear top. Unlike a traditional bikini top, a tankini top usually extends down over the torso, providing additional coverage while allowing the wearer to pair it with different bikini bottoms.

 

For swimwear brands, tankini tops offer plenty of room for customization. Different necklines, lengths, straps, fabrics, prints, and bottom combinations can create very different product directions.

What Is a Tankini?

A tankini is a two-piece swimsuit consisting of a longer top and a separate bottom.

The top typically covers part or most of the torso, making it different from conventional bikini tops such as:

Triangle Bikini Top

Bandeau Bikini Top

Underwire Bikini Top

Halter Bikini Top

The main characteristic of a tankini is its extended body length.

Depending on the design, a tankini top may end around the waist, hip, or lower torso.

Neither option is better. They simply communicate different design languages.

Different Tankini Styles

1. Neckline Design: The First Impression

The neckline is one of the most noticeable details of a tankini top.

Round Neck

A round neckline creates a clean and classic appearance. It can work well for simple, everyday swimwear collections.

V-Neck

A V-neck adds a more defined neckline and can create a feminine, elegant look.

Square Neck

A square neckline gives a tankini a more structured, contemporary appearance. It pairs well with minimalist fabrics and clean construction.

Halter Neck

A halter tankini creates a different shoulder and neckline shape, making it suitable for resort wear and fashion-focused collections.

The same tankini body can look completely different simply by changing the neckline.

2. Body Length: A Detail That Changes the Silhouette

Tankini tops can be developed in different lengths, including waist-length, hip-length, and longer coverage styles.

A shorter tankini top creates a more traditional two-piece appearance, while a longer silhouette gives the design a more coverage-focused direction.

Body length should be considered together with the bikini bottom. A high-waisted bottom can create a coordinated, retro-inspired look, while a classic or cheeky bottom can give the same top a more contemporary appearance.

For brands developing custom tankini swimwear, the desired length should be confirmed before pattern development and sampling.

3. Printed Tankini Design

Prints can transform a simple tankini into a distinctive seasonal product.

Popular design directions include:

Tropical and floral prints

Animal prints

Abstract artwork

Geometric patterns

Coastal-inspired stripes

Custom brand prints

A tankini can also use print placement to create a more intentional design. For example, a continuous print across the top and bottom can create a coordinated look, while a contrasting print can highlight the neckline or side panels.

4. Textured Fabrics and Color

Fabric selection is another way to change the visual identity of a tankini.

Ribbed fabrics can add texture and a more casual, contemporary feeling. Matte fabrics can create a clean and understated look, while metallic fabrics can bring a more statement-making resort wear direction.

Color combinations also influence the overall mood

Navy and cream: Classic and refined

Black and white: Minimalist and timeless

Pink and red: Bold and energetic

Green and blue: Fresh and vibrant

Brown and orange: Warm and earthy

The right fabric and color combination should match the brand’s intended positioning and collection concept.

5. Small Details That Make a Difference

A tankini does not need a complicated construction to become a distinctive product.

Small details can change its style, including:

Cut-Out Details

Cut-outs can introduce a more contemporary look while changing the visual balance of the garment.

Ruffle Details

Ruffles can add softness, movement, and a more playful or feminine appearance.

Decorative Hardware

Rings, sliders, and other accessories can create a more elevated finish. Their position and construction should be considered carefully during development.

Contrast Binding

Contrasting binding can highlight the edges of a tankini and create a sporty or graphic appearance.

Panel Construction

Different panels can add visual structure and create opportunities for color blocking or shaping details.

6. Tankini Design Ideas for Different Brand Directions

A single tankini silhouette can be adapted into different collections.

Minimalist Tankini

Clean lines, solid colors, and subtle branding create a simple and versatile design.

Resort wear Tankini

Tropical prints, decorative details, and coordinated bikini bottoms create a vacation-inspired collection.

Sporty Tankini

Contrast binding, secure straps, and practical construction can create a more active-inspired look.

Premium Tankini

Refined fabrics, structured cups, and carefully selected hardware can create a more elevated product direction.

Youthful Tankini

Bright colors, playful prints, and contemporary details can create a fresh and energetic aesthetic.

7. From Tankini Design to Custom Swimwear

For swimwear brands, a good design concept is only the beginning.

A custom tankini project may involve:

Design Concept → Fabric Selection → Pattern Development → Sample Making → Fit Review → Revision → Production

Before making a sample, it is helpful to confirm the neckline, body length, bust construction, fabric, lining, print, and matching bottom.

NIX INSIGHT

A tankini is not defined by its length alone. The neckline, body shape, fabric, and small construction details all contribute to its final look.
For swimwear brands, the same tankini silhouette can be developed into different styles through thoughtful design choices. A clean square neckline may create a minimalist aesthetic, while a printed fabric or ruffle detail can give the product a more expressive personality.
When developing a custom tankini, we recommend considering the overall balance between design, fit, and production feasibility. A beautiful detail should not only look good in a sketch, but also work well in the finished garment.
