We just got Wonder Woman's skirt (Drowned Amazon from the new Wondrous Time Capsule) It can fit really well for the Gal Gadot Wonder Woman or Rebirth. The Capsule also has the hair (Straight from the NPC). Tala will be a nice addition for sure
If you are paying for it, the broker has all of the versions, including the enhanced. The cost of them are pretty reasonable for a new time capsule style. You are looking for the leg style.
This skirt? It's actually reusing [Toga Bottom], the reward for the [Artemis Found] briefing from [Seeing Shades again]. You get the mission from [Gotham Under Siege], but all 4 pieces are found in the [Themyscira: Palace District]. No extra purchase is needed! Tala really needs an actual redesign instead of slapping on the dress and calling it done, I get that she doesn't get attention from DC anymore but it would be nice for her to have a genuine long slit dress that we can use too...
