I worked at Vicky's!
It was fun, the girls (and boys) always talked about sex, and that's where I got my start as a Faghag Supreme.
I learned that even though you may see your coworkers stealing, it's best to keep your mouth shut about it, NO MATTER WHAT THOSE VIDEOS SAY. But of course, tell the manager what they want to hear. Get used to seeing boobies and butts and don't put returned underwear back on the hangers--it happens with alarming frequency. Don't lie to the women about how they look, IME they'll buy from you when they know you're not handing them a bunch of BS. I racked up a lot of sales (and more hours) because of that I realized. You can tell a customer off and have your manager completely support if you have a good track record with customers and solid sales in proportion to your hours. Try not to take nasty customers personally, they often feel ugly inside and VS tends to attract people that are trying to use sex appeal to compensate.
Know the fragrances. Say things like base, middle, and top notes. Like if a woman was waffling about whether or not to buy Very Sexy, at the end of the day she'd smell the "subtle base notes" and whatever else stuff I'd say. Of course, you'd have to read the product info to know that and most Sales Associates didn't. Tell them you're especially good at keeping up with their policies regarding returns--cause you shop there! When telling the manager how you'd sell an item use really rich words. If you're selling a bra to a woman say rounded, high, plush not things like "that gives you good support!" That's non-descriptive. Say how the bra shapes and forms her body and what it does for it, not how comfortable it is. Once again, sexy is an image people are trying to emulate. Demo the makeup and wear VS products, especially lipsticks and glosses.
OK, I'm going to brag...I only worked on Friday nights for 4 hrs and and two 8 hr shifts on the weekends, but I was one of the top three Sales Associates in the store. Whenever I was on school break they always gave me a 40 hr schedule, so if you want to differentiate yourself from the other associates keep on top of the product knowledge, return policies, volunteer to stay after your shift if they need you too, don't steal customers from other associates, and above all be friendly and honest to the customers.
Good luck!
