Of course. What 'witch' wouldn't?

You decide to go into the store, Tiffany trailing behind you. "Um, are you sure you want to go in here?", she asks as you walk into the shop, which looks like it came straight out of a horror movie.

"Of course. I need a broom or something so people can tell I'm a witch." you say to Tiffany, discounting the decor of the store as something the owner did just for the holiday.

An old woman looks up from behind the counter. "Oh, you're a witch, dear? I'm surprised I haven't seen you before then." You blush a little bit, surprised that woman overheard you.

"Um, not a real witch, ma'am, I'm going as one for Halloween, and I just wanted to make it look more authentic.", you say timidly.

The old woman smiles. "Well, the first rule about being a witch is to be confident. I have the perfect charm for that," she says as she picks up a strange looking necklace from the display case. It looks like it is gold, but the charm looks like a naked woman with her legs spread, almost like she is presenting herself for her lover. "This is an ancient charm, that makes the woman who wears it into the most confident, sexy woman around. Some say that it belonged to famous women throughout history, such as Helen of Troy, Cleopatra, and Lady Godiva. Men will want you, and women will want to be you." You go to protest as the old woman puts it in your hand, but there is a sudden warmth as you touch it. It's almost like the necklace is alive!

"We'll take it!", Tiffany says as she pays for the necklace.

"Excellent. Be warned though. It is very old magic, and few know what it can do to a person," the old woman explains.

You nod. "Thanks for your help. I'm sure it will add, um, something to my costume, " you say as you shoot a glare at Tiffany. You were supposed to find an old broom or a spell book, but this? While you liked how it felt, you weren't sure about wearing a necklace like this to the party.

Tiffany shrugs, and you both leave the store, going back to the dorm. The rest of the day is uneventful, and you fall asleep, the new necklace on your nightstand, by the bed.
