Hotaru stays near the door, watching people mill around, feeling awkward. She wasn't used to big groups, and this, this was the entire population of Luceti, or Luceti Land.

Her outfit seems to be modeled off her Senshi uniform, and Tuxedo Mask's own clothes. The skirt's the same, as is the boots, though the top is looser, with a purple bow-tie instead of giant chest bow. She's even got a little white cape-purple on the inside- and domino mask to complete it. Look, it's Saturn Mask~

... A very uncomfortable Saturn Mask. She'd rather be at home guys. Or at least upstairs where she could be alone.
