Investing in high-quality clothing is only half the battle; knowing how to care for it is what makes your favorite pieces last for years. From breathable cotton to delicate silk, every fabric requires a specific touch.

In this master guide, we’ll break down the best washing methods for different fabrics to keep your SML Intimate collection in pristine condition.



1. Natural Fibers: The Breathable Essentials


Cotton

Cotton is durable but prone to shrinking.
  • Wash:Cold or lukewarm water.
  • Tip:Wash dark cotton inside out to prevent fading.
    

Silk

The queen of fabrics requires royal treatment.
  • Wash:Hand wash only with a dedicated silk detergent. Never wring silk.
  • Dry:Lay flat on a clean towel away from direct sunlight.
  • Tip:Add a spoonful of white vinegar to the rinse water to maintain its shine.



2. Synthetic & Performance Fibers: The Everyday Comfort


Polyester & Nylon

Common in activewear and bras, these are durable but can trap odors.
  • Wash:Machine wash in warm water with an all-purpose detergent.
  • Dry:Tumble dry on low or air dry to avoid static cling.
    

Spandex (Elastane)

Found in almost all intimate apparel for stretch.
  • Wash:Hand wash or use a mesh laundry bag on a delicate cycle. Never use bleach, as it destroys the elastic fibers.



3. Semi-Synthetics: The Soft & Silky


Modal & Tencel

Known for their incredible softness in loungewear.
  • Wash:Cold water on a gentle cycle.
  • Dry:Air drying is highly recommended to maintain the "silky" feel.



4. Special Care for Intimates (The SML Way)


Your bras and delicate lingerie deserve extra attention.
  1. Use a Mesh Bag:Always protect lace and straps from getting tangled.
  1. Avoid Fabric Softener:It can break down the elasticity in bras and underwear.
  1. Cool Water Only:Heat damages the delicate fibers of high-end intimates.
