Battery Installation Tips:
Battery Box (skirt waist): Please prepare 3 × 1.5V AA batteries (not included).
Use a screwdriver to loosen the screws.
Slide open the cover in the direction of the arrow.
Insert the batteries according to the positive (+) and negative (–) markings. (Wrong installation will cause the lights not to work.)
Close the cover and tighten the screws securely.
Plug in the USB cable and switch it on to enjoy the glowing effect.
Remote Control: Requires 1 × CR2025 button battery (not included). Make sure to install it with the correct polarity (+/–).
Cleaning Recommendations:
Remove the batteries from the battery compartment before washing.
Hand wash only — gently scrub the dress. Avoid vigorous rubbing to prevent glitter from coming off.
After washing, air dry the dress. The light strip is waterproof, so it’s safe to wash, but do not pull or twist it. Try to keep the battery box as dry as possible.
Before wearing again, make sure the battery compartment is completely dry. If any moisture remains, use a hair dryer to dry it fully before reinserting the batteries.
