Use gains.
When the reader chooses their outfit/hair put in gains like this:
choice
“Purple Dress” {
gain purple_dress
goto label
} “Pink Shirt” {
gain pink_shirt
goto label
} “Green Skirt” {
gain green_skirt
goto label
}
This way, later on in the story when you want them to change back to the outfit the reader chose you can just:
if (purple_dress) {
@/CHARACTER changes into Purple Dress
} elif (pink_shirt) {
@/CHARACTER changes into Pink Shirt
} elif (green_skirt) {
@/CHARACTER changes into Green Skirt
} else {
}
It’s the same for the hair as well
