I thought about them changing clothes to go to Rosestone, but then I thought, but Nyna isn’t going to change, so if they were together it makes more sense for them to wear the same style. Also – Some unexplained lore! Kaylin’s armor is Glamoured. Also called Transmog, she has some items that let her make her armor appear as a type of clothing or other armor. Normally those items were destroyed after use, but, now they seem to be self recharging. Had to cut that scene back at the time when she got the yukata to begin with. It has the same stats and abilities as her old spider-web leather top. The bracers are different, still protective, but not the same abilities.
