Tisarwat really needed to get out more, and Summer was a friend, even if they hadn't been hanging out as much anymore ever since she and Lucille moved in together and Seivarden ran off with Breq, subsequently abandoning her here. And this party always was good for just getting completely wasted, which Tisarwat also hadn't done in far too long, either. So she hoped an ugly jacket would suffice in lieu of a sweater, especially since she paired it with some horrendous gloves.
