"Maybe there's a spell for that..." Even as he says this, though, Jarlaxle will feel a subtle shift. His skin begins to glint with flecks of light, like sun-dazzle on water. His clothes... well, Laios is terrible at picturing fancy clothes with any specificity, but there's some hint of lace and brighter colours?? More importantly, Jarlaxle can feel that he could easily take the reins of this transformation and appear however he wants, here and now. It is a dream, after all, and Laios wants his happiness.
