Well, Luceti does have a clothing shop in the plaza that helpfully provides any clothes you might need--some of them belong to other residents from when they first arrived here, though it does also provide other outfits as well. There's also a place of fashionable taste called "All Passions" that has clothing made by some of the residents themselves, if the other shop doesn't have what you're looking for.

[Basically, the Luceti one is where you go if you are missing any clothing items you had from before you arrived, where as All Passions will make its own clothing for you rather than relying just on whatever happens to show up conveniently in the other place.]
