How to Care for Your Backless or Adhesive Bra

Keeping your invisible lingerie clean ensures it stays sticky and supportive for longer.

Do’s:

• Gently wash with mild soap and warm water after each wear.
  
  

• Let it air dry with adhesive side up.
  
  

• Store with plastic covers to protect the adhesive.
  
  

Don’ts:

• Avoid lotion or oil on your skin before applying—it weakens the grip.
  
  

• Don’t machine wash or expose to high heat.
  
  

💡 Bonus tip: Replace adhesive bras every 20–30 wears for best performance.

• Under backless tops: Try a convertible bra with clear or low straps.
  
  

• For bridal wear: Pick a nude push-up adhesive style for invisible lift.
