The costume store is dimly lit, and as you enter you have to adjust your eyesight for a couple of seconds. The place is packed full of costumes, but you can't see a single customer. Or the proprietor, for that matter
"Hello?" you say, uncertainly. After a few seconds, an man in his fifties appear from behind one of the racks of costumes.
"Ah, good day!" he says. "What can I help you with?"
"Well, uh, I have a bit strange request." You're a bit embarrassed by what you are about to ask him, but you try to stay calm and focused. "You see, my girlfriend, she, well, she likes to dress up. Likes to do role-reversal roleplay. You know, where she's the man. I always felt weird about it, so we don't do it much, but she said maybe if we had the right costumes, it would help me get into it. She suggested your shop, and, well, I promised her I would stop by and ask."
"No, no, don't worry. I have heard far stranger requests than that. When you've been in my business for as long as I've been, and with costumes as good and lifelike as I sell, you meet the strangest of people. Why, last week I sold a pair of dog costumes to a husband and wife older than me. So don't feel ashamed. I'm quite sure I have something for you.
What you want is one of my paired costumes. One for yourself, and one for your girlfriend. Now, the standard costumes in this category are not designed for someone of the opposite gender to wear, so you will have to upgrade to one of the deluxe versions. They have a steep price, about $500 for the pair, but they also come with a guarantee of satisfaction. As long as they're not damaged, you can come back with them within a week and get your money back, minus a small sum of $30 for cleaning and replacement of parts that I can't resell."
"Sounds fine," you say. "My girlfriend is kinda loaded, and she suggested it, so..."
"Excellent. Now, what costumes are you interested in? I can probably get you almost anything you can think of. Boss and secretary, boss and maid, stripper, knight and fair maiden, even some master and slave costumes."
