Last night I remembered a story I read (I think on here) that I cannot remember who wrote it, or a title... Premise was boy was roped in with his cousin(?) to help clean out an aunt or other family members house. As they did so they came across a series of dresses she had made that he then tries on since he's a doppleganger for the person she designed them for after being pushed into it by the cousin. The story revolves around those dresses and finding them since they're numbered and in an order as they clean out the house. Eventually SHE admits she's tg and moves forward.
