How Do You Know If a Swimsuit Is Good Quality?

Not all swimsuits are created equal. From fabric to stitching and fit, many factors distinguish a high-quality swimsuit from one that wears out quickly. In this article, we explore how to evaluate swimwear quality and how custom options can help ensure both durability and personal style.

What Fabrics Indicate a High-Quality Swimsuit?

Blend Matters

High-quality swimsuits typically consist of a blend of nylon (polyamide) and elastane (spandex). Aim for at least 15–20% elastane to ensure flexibility and durability.

Chlorine and UV Resistance

Premium fabrics frequently incorporate chlorine resistance or UV-blocking features to prolong the life of the garment. Explore options from brands like Lycra® and Carbon Swimwear.

Touch and Feel

Good fabric feels smooth, thick, and supportive—not scratchy or thin. Quality textiles bounce back quickly after stretching.

Fabric Type Elasticity Durability Resists Chlorine
Nylon + Elastane High Moderate No
Polyester + PBT Medium High Yes
Recycled Lycra® High High Yes

How Does Construction Affect Swimwear Quality?

Stitching Techniques

Choose garments with reinforced flatlock or zigzag stitching. Poorly constructed seams and loose threads indicate subpar manufacturing. High-quality construction prevents fraying.

Double Lining

More expensive swimsuits are frequently lined on the front or entirely to prevent see-through areas and enhance support and comfort.

Elastic and Reinforcement

Waistbands, straps, and leg openings should include strong elastic that holds without digging into the skin.

Construction Element Quality Indicator What to Avoid
Stitch Type Flatlock / Zigzag Loose single seams
Lining Front or full-body No lining, see-through
Elasticity Snug, durable stretch Overly loose or brittle

Why Is Fit a Key Indicator of Quality?

Supportive Fit

Quality swimwear should provide support without constraining movement. Seek out suits that remain secure during activity, particularly when being used actively.

Retention Over Time

High-quality suits maintain their shape after multiple washes. If it bags, sags, or stretches out quickly, it's not worth your money.

Size Consistency

Reliable brands offer consistent sizing charts. If your size fluctuates between colors or styles, the manufacturing process may lack quality control.

Fit Feature Sign of Quality Concern If Missing
Snugness Secure, flexible hold Loose or baggy areas
Shape Retention Maintains over time Sags after washing
Size Accuracy Consistent across models Random fitting
