"If you want clothes, the spider's your best bet." It's half a guess. He can't quite hear what she's muttering, but she's sorting through clothes and that's enough for him to make an educated guess. "You leave an offering in her carriage and she'll make whatever you want, from what I hear."

He could offer to do it too, but it's easier to offer someone else up for this specific thing. Clothing's weird for him. He can do it, but they're almost invariably weird in a way that he doesn't want to have to explain if it ever comes up.
