In the hyper-competitive swimwear market, differentiation is everything. For decades, designers relied on two primary tools to stand out: print and silhouette. But in recent years, a third, more tactile dimension has emerged as a dominant force, transforming the look, feel, and perceived value of swimwear: texture.
From the ubiquitous ribbed knit to intricate smocking and sporty waffle weaves, textured fabrics have moved from a niche trend to a market staple. For swimwear designers and brands, understanding this category is no longer optional—it’s essential for creating collections that look, feel, and sell as premium.
This article is your definitive guide. We’ll dive deep into what textured swimwear fabric is, explore the most popular types, and cover the critical design and technical considerations you need to know to work with it successfully.
Why Is Textured Fabric Dominating Swimwear?
First, let’s define our terms. Textured swimwear fabric is any swimwear-grade material that is not perfectly smooth. Its surface has been manipulated—through knitting, weaving, or finishing—to create a three-dimensional pattern, pile, or hand-feel.
Crucially, this is not just any textured fabric. To be “swimwear-grade,” it must still possess the non-negotiable performance properties:
4-Way Stretch & Recovery: Excellent elasticity, typically from Lycra, Spandex, that snaps back to its original shape.
Durability: High resistance to chlorine, saltwater, pilling, and UV rays (which cause fading).
Opacity: Must remain opaque when wet and stretched.
Quick-Dry: Must not hold excessive water.
The rise of this trend isn’t accidental. It’s a response to several key market drivers:
Perceived Value: Texture instantly signals “premium.” A solid-color ribbed bikini simply looks more expensive and thoughtfully designed than a flat solid-color bikini.
Sensory & Haptic Appeal: In a digital world, consumers crave touch. The “hand-feel” of a fabric—its softness, structure, or crinkle—creates an emotional connection and a more luxurious experience.
Flattering Fit: Texture is magic for fit. Ribs create vertical lines that elongate, while smocking and crinkles are incredibly forgiving, stretching to fit a wider range of body types and masking imperfections.
The “Swim-to-Street” Blur: A waffle-knit swim top doubles as a crop top. A terrycloth one-piece pairs with denim shorts. Texture blurs the line between swimwear and resort wear, giving the garment added versatility and value for the consumer.
Types of Textured Swimwear Fabrics
Working with texture begins with understanding your options. Each fabric type has a unique aesthetic, stretch quality, and set of design challenges.
1. Ribbed Knits (The Timeless Classic)

This is the gateway to texture and the most popular style by far. A ribbed knit is created with a specific knit structure (like a 1×1, 2×1, or 2×2 rib) that forms vertical “valleys and hills.”
Aesthetic: Clean, classic, athletic, and universally flattering. It can skew sporty or sophisticated.
Design Considerations:
Stretch: Ribs primarily stretch horizontally (width-wise). This is fantastic for a snug fit but be mindful of your patterns. You may need less horizontal ease than with a standard flat knit.
“Grinning”: This is a critical technical challenge. “Grinning” is when the fabric is stretched and the base of the knit (often a different color, like white) “grins” through. Always source high-quality, yarn-dyed ribs to avoid this.
Weight (GSM): A light rib (180-220 GSM) is great for simple tops, but a heavier rib (250-300+ GSM) provides more compression and a more “luxe” hand-feel.
2. Smocked & Shirred Fabrics (The Ultimate Stretch)

Smocking creates a tightly puckered, gathered texture with incredible elasticity. This is traditionally done by stitching elastic thread into the fabric (shirring) or through a specialized knit process.
Aesthetic: Romantic, vintage, feminine, and playful.
Design Considerations:
One-Size Potential: The high degree of stretch makes smocked fabric a popular choice for “one-size-fits-most” or flexible-fit collections, which can reduce your SKU complexity.
Bulky Seams: This is the #1 challenge. Seams can become extremely thick. You must use flat-lock stitching or a high-quality overlock. You may also need to adjust patterns to move seams to less-critical areas.
Lining is Essential: The “valleys” of the smocking can become sheer when stretched. A full, high-quality flat lining is required for opacity and support.
This category includes all “puckered” or “bubbled” fabrics. True seersucker is a woven fabric with alternating slack-tension yarns, but in swim, this texture is often achieved with a knit construction or a chemical finish.
Aesthetic: Effortless, retro (’80s and ’90s), and “undone” chic. It’s brilliant at hiding wrinkles from being packed in a suitcase.
Design Considerations:
Growth: This fabric “grows” when wet. Test your swatches rigorously. You may need to cut your pattern slightly smaller to account for this.
Recovery: Pay close attention to the recovery. A cheap crinkle will “bag out” after one wear. Ensure it’s blended with a high-percentage, high-quality spandex.
Lining: A structured lining is essential to provide the support and “scaffolding” that the looser crinkle fabric doesn’t offer on its own.
4. Waffle Knits (Sporty & Sophisticated)
A 3D, thermal-style knit with a grid-like or honeycomb pattern. Once reserved for long-johns, it’s now a high-fashion staple.
Aesthetic: Sporty-luxe, minimalist, and structured. It lends itself perfectly to more “architectural” silhouettes.
Design Considerations:
Structure: Waffle knits often have less “drape” and more “body.” This is excellent for creating structured tops or smoothing one-pieces, but less ideal for “stringy” or ruched designs.
Water Retention: The small “pockets” can hold slightly more water than a flat fabric. Ensure you’re sourcing a poly-based or performance waffle, not a cotton-based one, for quick-dry properties.
5. Jacquard & Dobby Knits (Woven-In Elegance)
This is the most premium, “couture” level of texture. In a jacquard, the pattern (floral, geometric, animal print) is knitted into the fabric structure itself, rather than being printed on top.
Aesthetic: Luxurious, elevated, and rich. Allows for “print” without printing.
Design Considerations:
Cost: This is a more complex and expensive manufacturing process, so the fabric cost will be higher. This is for your high-end or capsule collection.
Stretch: Complex jacquards sometimes have less stretch than simpler knits. Check the 4-way stretch specifications from your supplier.
Snagging: Depending on the knit, “floats” (long yarns on the back) can be prone to snagging. A full lining is non-negotiable to protect the yarns and the wearer’s skin.
6. Terrycloth (The Toweling Trend)

A fabric with a looped pile, just like a towel, but engineered for swim. It’s almost always a knit-terry (like a French Terry) for stretch, rather than a woven-terry.
Aesthetic: ’70s retro, playful, and perfect for “lounge-focused” swim.
Design Considerations:
Absorbency: This is its pro and con. It’s soft and cozy, but it will absorb more water and be heavier when wet. This makes it better for “cabana” or “boat” suits rather than serious performance swimming.
Pile Direction: The “loops” have a direction (nap). You must cut all pattern pieces in the same direction, or the light will reflect differently, making them look like two different colors.
Designing with Textured Swimwear
Choosing the fabric is step one. Successfully manufacturing with it is step two. Textured fabrics are not “drop-in” replacements for flat fabrics; they require adjustments to your design and production process.
Pattern Making & Fit
Adjust for Bulk: Textured fabrics are thicker. You must add more “ease” to your patterns or “scoop” your curves (like armholes and leg-holes) to accommodate the fabric’s bulk. If you don’t, the garment will fit tighter and smaller than its flat-fabric counterpart.
Test Stretch Direction: A rib’s stretch is different from a smock’s. Always make a sample and test the fit. You may need to create a separate pattern “block” specifically for your textured styles.
Construction & Seams
The Bulky Seam Problem: This is the most common pitfall. A four-way seam (e.g., where a strap, body, and lining meet) with a thick waffle knit can become a “rock.”
Flatlock Stitching. This creates a flat, strong seam, but requires a specific machine.
“Grade” Your Seams. Manually trim the seam allowances at different lengths to “feather” the bulk.
Use Clear Elastic. Use high-quality clear elastic (like Framilon) in your seams (especially leg holes and straps) to provide support without adding fabric bulk.
Lining is Non-Negotiable
Do not try to save money by not lining textured swim. It’s a fatal error.
Opacity: Many textures “grin” or “valley” when stretched, becoming sheer.
Support: The lining is the true “support” layer. A high-quality, compressive lining (like a power-mesh or a smooth recycled nylon) provides the structure, while the textured fabric provides the “fashion.”
Comfort: The lining provides a smooth, soft layer against the skin, preventing any rough jacquard-backs or scratchy elastics from irritating the wearer.
Conclusion
Textured swimwear fabrics bring personality, performance, and premium appeal to modern collections. They offer endless creative freedom—from minimal ribbed bikinis to statement jacquard one-pieces—while enhancing comfort and durability.
Whether you’re launching a boutique line or expanding your product range, experimenting with texture is one of the easiest ways to elevate your designs and captivate customers.
