Assuming that the last clothes I was wearing are what will be here, it's a long-sleeve dress made of velvet, alongside a pair of tights and black shoes. It... should be purple.

[At least, she's assuming it was purple. She'll just be walking into the store and feeling all the clothes until she finds something velvet.]

...although, seeing as I will be wearing more than one dress the rest of my life, I should also search for anything that might fit. [And anything that isn't ridiculous looking. Clothes shopping is hard when you can't see the clothes!]
