Amaya had been debating a little about whether or not to come to the wedding; she wasn't really the wedding going type, if she could help it. But Prompto had been a student (and a good one at that), and she'd worked with Liz a little, and she had been invited, and she did have that whole thing about having all those nice clothes and not letting them go to waste, so she was there, feeling a bit awkward about it, and, yes, that was the same dress she'd worn to the last wedding. Why would you need to wear a different one when you already had a perfectly good one already?
