The only one that was smaller was the Faun, which Brent/Luke picked up. The clerk shrugged. "It is one of the few I have left that is supposed to fit anyone. Though I never tried it with someone who has been changed. Give it a shot."
Brent/Luke was already stripped, so he tried sticking one of his huge feet in the leg opening. It hung up at first, and he thought it might not change for him, but then his foot and leg slid in. He pulled on the other side, and for a moment, looked really odd, his human half dominating hugely over his goat half. Then he flipped the human part of the costume up and slipped his arms into the slots. As he did, the head flopped forward and covered Brent/Luke's face. With a shudder, the faun opened its eyes. It looked like a 13-year-old boy with a goatee and full goat's hindquarters, including an impressive billy goat's equipment.
He trotted around and then looked down. "It is weird to be so much smaller, but I have to admit I feel really horny. What do I do?" As he said that, two portals appeared: One led to a field of goats, the other opened into a wooded glen with fauns, satyrs, and nymphs cavorting. The clerk frowned. "Be really careful. You might end up as a beast or a faun forever with either of those choices. It would be safer to stay here."
