How to Wash a Swimsuit So It Doesn't Stretch Out Easily? Your Complete Care Guide for 2026
Did you buy a favorite swimsuit only to find it getting loose, misshapen, or faded after just a few wears? Actually, swimsuits aren't as fragile as you might think; often, we just use the wrong care methods. Whether you prefer a bikini or a one-piece swimsuit, by following the correct washing and drying steps, you can truly double your swimsuit's lifespan. This time, we'll walk you through the simplest ways to keep your swimsuit elastic and prevent it from stretching out easily.
Why Do Swimsuits Stretch Out So Easily? Understand the Material Properties First
Swimsuits owe their elasticity, snug fit, and comfort to elastic fibers like Spandex or Lycra. However, these fibers are quite delicate and will gradually degrade and lose elasticity when exposed to chlorine, salt, high temperatures, and UV rays.
NAMI swimsuits are intentionally made without strong color-fixing agents to ensure user safety, which means they may experience color bleeding when wet and will fade over time. However, this is to avoid chemical irritation to the skin, making them more skin-friendly and safer.
If you continue to wash them incorrectly—for example, using hot water, harsh wringing, machine washing, or tumble drying—you will accelerate fiber relaxation, and your swimsuit will quickly lose its support and elasticity.
Correct Swimsuit Washing Steps: Rinse with Water, Air Dry Naturally
Step 1 — Rinse Immediately with Clean Water After Wearing
After leaving the pool or beach, don't wait until you get home to wash it. Immediately rinse off chlorine, salt, and sunscreen residue with clean water to prevent chemicals and minerals from sitting on the fibers for too long and eroding their elasticity.
Step 2 — Hand Wash with Cold or Room Temperature Water
Back at the hotel or home, gently press the swimsuit with cold or room temperature water. Do not use hot water—hot water will destroy the structure of elastic fibers. Remember not to wring it harshly; a gentle press is enough to remove dirt.
Step 3 — Do Not Use a Washing Machine or Dryer
Washing machines can stretch and deform fibers, and the high heat from dryers will directly destroy elasticity. No matter how rushed you are, do not take the easy way out by machine washing or tumble drying.
Step 4 — Air Dry Naturally, Avoid Direct Sunlight
After washing, lay flat or hang with two hangers to avoid single-point stress that can stretch shoulder straps or bottom edges. Air dry in a cool, well-ventilated area, and do not expose to direct sunlight—UV rays will cause colors to fade faster and elasticity to be lost.
Swimsuit Drying Tips: Use Two Hangers to Prevent Deformation
Many people simply hang their swimsuit with one hanger, but this causes single-point stress on the shoulder straps or waistline. Wet swimsuits are particularly heavy and can easily stretch and deform.
The correct method is to use two hangers to distribute the weight: one for the shoulder straps and one for the bottom edge, or lay the swimsuit flat on a drying rack. This helps maintain the swimsuit's original shape and prevents deformation. Remember to choose a cool, well-ventilated area and avoid direct sunlight.
Practical Example: Assuming You Are a 158cm Plus-Size Woman, How Do You Care for Your Swimsuit?
Let's say you've chosen a supportive one-piece swimsuit and wore it to the beach for swimming, photos, and sunbathing. After returning to the hotel, immediately rinse off sand and salt with the shower, then gently hand wash with cold water, avoiding harsh wringing.
Afterward, hang it with two hangers in a shaded spot on the balcony, avoiding direct sunlight to prevent colors from fading faster. By following these steps, your swimsuit can maintain its elasticity and support, accompanying you all summer long.

Avoid These Common Mistakes to Double Your Swimsuit's Lifespan
- Mistake 1: Not washing immediately after wearing, allowing chlorine or salt to remain for prolonged periods, accelerating fiber degradation.
- Mistake 2: Using laundry detergent or bleach, as chemicals will erode fibers, causing the swimsuit to lose elasticity.
- Mistake 3: Harshly wringing dry or wrapping in a towel to absorb water, leading to deformation and stretching.
- Mistake 4: Hanging in direct sunlight, as UV rays rapidly diminish elasticity and cause colors to fade.
