There are cute dresses and such present in the game, but they're largely not available to players, so I made a mod for it.

You can install using the Baldur's Gate 3 Mod Manager.

They're available as both Camp slot items, and as Armour. You can acquire the Camp slot dresses in game from the Tutorial Chest found during the prologue, and the camp slot and armour slot versions may both be purchased from Dammon in the Druid's Grove. They all come in Black by default.

Otherwise here are their UUIDs

Lastly, a brief thank you to AnteMaxx and Druundev for their guides and such, it was incredibly helpful.
