Quick answer

Hand wash your DIM shapewear in cool water with a mild detergent, then air dry flat away from heat. Never use bleach, fabric softener, or the dryer—these break down the microfibre and elastic that give the garment its sculpting effect.

Why shapewear needs special care

DIM shapewear, like the Silhouette Invisible string, uses fine microfibre and high-recovery elastic to smooth and sculpt. Harsh washing or heat can permanently relax the fibers, reducing the "effet ventre plat" and overall fit. A little gentleness goes a long way.

5 steps to wash DIM shapewear safely

  1. Turn the garment inside out: This protects the outer microfibre from friction and pilling. It also lets water reach the areas that touch your skin most. Checkpoint: If you see pills or fuzz on the outside, you may have skipped this step.
  2. Fill a basin with cool water (below 30°C / 86°F): Hot water weakens the elastic fibers that create the sculpting effect. Use a sink or bowl—no soaking in the tub for hours. Mistake: Hot water is the #1 cause of saggy shapewear.
  3. Add a small amount of mild detergent: Use a lingerie wash or a gentle liquid soap. Never pour detergent directly on the fabric—dilute it first. Avoid bleach, fabric softener, and stain removers. Checkpoint: If the water becomes cloudy or sudsy, you used too much soap.
  4. Gently swish and soak for 5 minutes: Do not rub, wring, or twist the fabric. Submerge and move it gently. Let it sit for up to 5 minutes—longer soaking can loosen the fibers. Mistake: Scrubbing the waistband area can break the internal elastic threads.
  5. Rinse with cool water and press out moisture: Rinse until no soap remains. Lay the shapewear on a clean, dry towel, roll it up, and press gently to remove excess water. Never twist or use a spin cycle. Final step: Air dry flat away from direct sunlight and radiators. Do not hang—gravity stretches the waistband.
