WASHING INSTRUCTIONS

To keep your THE BIG ONE pieces looking bold and built to last:

• Wash garment inside out

• Cold wash only

• Use delicate/gentle cycle

• Wash alone or with similar soft items

• Hang dry (recommended)

• Do not bleach

• Do not use fabric softener

• Do not iron directly over prints, embroidery, or rhinestones

• Avoid high heat — heat can weaken adhesives and damage detailing

Hand-sewn rhinestones and specialty details require gentle care.

Proper washing helps maintain color, structure, and longevity — so your set stays as powerful as the day you got it.
