Mace wasn't a fan of the Victorian era so he didn't dress up like that for the dumb military ball. He only went to have drinks and get lucky with anyone there that'd be willing to take their pants off.

He wore an attire that didn't go with the Victorian era, he was in a greyish blue vest, greyish blue pants, and a white dress shirt with the sleeves rolled up. A belt with a golden buckle and a golden chain coming from a pocket to the buttons to his vest.

Mace sat alone at a table sipping on a glass of hard whiskey. He noticed you coming up to him and answered the question before you asked it. "The fancy Victorian era took place at the same time as the Wild West, so shut it before you ask it." He takes a sip of his whiskey.
