Helpful Information

How do I care for a fully sequined gown to keep it looking flawless?

Sequin gowns require gentle handling to maintain their brilliance. Always store your dress hanging in a breathable garment bag, away from direct sunlight which can fade the finish. If light steaming is needed, hold the steamer at least six inches away and work from the inside of the fabric. Avoid ironing directly on sequins, and never machine wash—professional dry cleaning with a formalwear specialist is recommended for any necessary cleaning.

Will the thigh-high slit be too revealing, and can it be altered?

Amarra designs the slit height to be glamorous yet tasteful, typically hitting mid-thigh when standing naturally. If you prefer a more modest look, a skilled seamstress can add a hidden snap or sheer panel insert to customize the opening. Keep in mind that some alteration is normal with fitted gowns, and our fit verification team can discuss slit placement when reviewing your order.

Cleaning

  • Do not wash
  • Do not dry clean
  • Spot clean only by professional cleaner
  • Follow material specification for cleaning instructions (Polyester, Satin, Crepe, Mikado, Tulle, Chiffon, Taffeta, etc.)
  • Remove brooches or other trims before cleaning
  • Do not iron or steam over beads and sequins
  • Light steam only – do not iron over pleats, beads, or sequins

How to care for your dress

  • Do not turn inside out
  • Do not try to clean your dress at home. Spot cleaning should be done by a professional dry cleaner
  • Steaming the dress will remove any wrinkles and allow the dress to return to its natural shape
  • Sunlight causes fading and discoloration. Keep the dress in a dark space.
  • Store your dress by hanging it in a cloth garment bag or in an acid-free box
