White Tuxedo Shirt

The Clothier is the only source and he lists it on the night of a full moon. That is a narrow window on two axes: the moon has to be full and the sun has to be down, so checking his stock at midday on the right day shows you nothing. Bring enough coin for both pieces in one trip, because the next opening is a full moon cycle away.

Two pieces, both cosmetic, both for the social slots. It is the pale counterpart to the standard black Tuxedo Shirt and Tuxedo Pants, and mixing across the two is the usual reason to own both: white jacket with dark trousers, or the reverse.

Old-gen console and 3DS have the set sitting in the files with no way to obtain it, so on those versions treat it as absent.
