CrossDresser

CrossDresser is a program by EvilInnocence that is designed to convert wardrobe items for one figure so that they can be used with a different figure. The program itself is free, and available at the EvilInnocence website.

However, the program requires licenses to export wardrobe items for use with particular figures. Free licenses are available on the same website for these figures:
 * Evelinne
 * Grey Alien
 * Jinkie
 * Krystal Starfox
 * Mannequin
 * P4 Boy
 * P4 Girl
 * P5 Don
 * P5 Judy
 * P5 Penny
 * P5 Will
 * Pippin Basket
 * Preteen Boy
 * Preteen Girl
 * Sara
 * Vixie
 * Wapi Pu

Paid licenses are available for over a hundred other figures.
