Scuba fabric has become one of the most popular choices in modern garment sewing — and if you haven't worked with it yet, you're in for a treat. Smooth, stable, and surprisingly versatile, scuba is a fabric that punches well above its weight. Here's everything you need to know.
What Is Scuba Fabric?
Scuba fabric is a double-knit fabric typically made from a polyester-spandex blend (usually around 95% polyester and 5% spandex, though blends vary by manufacturer). It has a smooth, matte surface on both sides, a substantial weight, and a firm but comfortable stretch. Despite its name, scuba fabric has nothing to do with diving — the name comes from the fabric's similarity in structure to neoprene, the material used in wetsuits.
Scuba is sometimes called scuba crepe or techno fabric, and is closely related to ponte knit — though scuba is generally smoother, heavier, and more structured than ponte.
Key Characteristics of Scuba Fabric
-
Smooth, matte surface: Scuba has a clean, refined appearance with no visible texture — it photographs beautifully and looks polished in finished garments
-
Substantial weight: Heavier than most knit fabrics, scuba has excellent body and holds its shape without boning or heavy interfacing
-
Controlled stretch: Scuba stretches but has good recovery — it bounces back to its original shape rather than bagging or stretching out permanently
-
Wrinkle resistant: Scuba is remarkably resistant to wrinkling — a significant advantage for travel and all-day wear
-
Doesn't fray: Like all knit fabrics, scuba doesn't fray when cut, simplifying construction and finishing
-
Opaque: Scuba is fully opaque — no lining required for most garments
What Is Scuba Fabric Used For?
Scuba's combination of structure, stretch, and smooth surface makes it ideal for a wide range of garments:
-
Bodycon dresses and skirts: Scuba's weight and recovery make it perfect for fitted, structured styles that hold their shape all day
-
Pencil skirts: One of the most popular uses — scuba creates a sleek, professional pencil skirt with minimal effort
-
Structured tops and blouses: The fabric's body allows it to hold structured design details like peplums, tulip hems, and box pleats
-
Jackets and blazers: Heavier scuba works beautifully for unlined jackets and structured blazers
-
Occasion and formal wear: Scuba's polished appearance makes it well-suited to cocktail dresses and event wear
-
Cosplay and costume construction: The fabric's structure and smooth surface make it popular for costume builds that require a sleek, defined silhouette
Advantages of Sewing with Scuba Fabric
-
Beginner-friendly despite its premium look: Scuba is stable and doesn't shift or slip under the needle the way rayon or chiffon does
-
No lining needed: Scuba is thick and opaque enough to wear without a lining in most applications
-
No hemming required: Scuba edges don't fray, so raw hems are acceptable — though a turned and stitched hem gives a more polished finish
-
Minimal pressing: Scuba wrinkles don't set in the way woven fabric wrinkles do — most wrinkles shake or hang out without pressing
-
Holds design details: Peplums, structured hems, and sculptural details hold their shape in scuba without boning or heavy interfacing
Tips for Sewing with Scuba Fabric
Use the Right Needle
Use a ballpoint or stretch needle (size 75/11 or 90/14) to sew scuba. A standard sharp needle can skip stitches or damage the knit structure of the fabric.
Use a Stretch Stitch
While scuba is more stable than most knits, seams still need some stretch. Use a narrow zigzag stitch, a stretch stitch, or a serger for seams that will be under stress. A straight stitch alone can pop in seams that don't have enough give.
Cut with Sharp Tools
Use a sharp rotary cutter or very sharp fabric scissors. Scuba's thickness and density can dull blades quickly — a sharp blade gives you clean, accurate cuts.
Pin or Weight Carefully
Scuba is heavy enough that it can shift during cutting if not secured properly. Use pattern weights or plenty of pins to keep pieces in place while cutting.
Press with Low Heat
Scuba is polyester-based and can melt or shine under high heat. Use a low iron setting and always press with a pressing cloth to protect the fabric surface. Steam can help ease out any persistent wrinkles.
No Pre-Washing Needed
Scuba fabric made from polyester doesn't shrink significantly, so pre-washing is generally not necessary. If you prefer to pre-wash, machine wash on a gentle cold cycle and tumble dry low.
Scuba vs. Ponte Knit — What's the Difference?
-
Weight: Scuba is generally heavier and more substantial than ponte
-
Surface: Scuba has a smoother, more matte surface; ponte has a slightly more textured appearance
-
Stretch: Ponte typically has more stretch than scuba; scuba has better structure and recovery
-
Uses: Both are used for similar garment types, but scuba excels in structured, bodycon styles while ponte is more versatile for flowy and draped designs
Care Instructions for Scuba Fabric
- Machine wash on a gentle cycle in cold or warm water
- Tumble dry on low heat or hang to dry
- Avoid high heat in washing, drying, and ironing
- Store folded or hanging — scuba resists wrinkles and stores easily
