Remember invading department stores to try on prom dresses? Recapture that wild princess feeling by going on a shopping date with your girlfriends. It doesn't matter if you're closer to 30 than 13. Hit the juniors section, try on an obscenely expensive ball gown or duck into a designer shoe shop for a stiletto fashion show.
Make it a thing
When you were a teen, you probably didn't do much in the way of organizing shopping dates with your friends. Now that you're an adult, make sure you plan ahead enough for everyone to have time to secure a babysitter or arrange for time off work. Use a free online invitation service to organize your shopping date. Try giving it a theme, like Pretend Prom.
Dress for the occasion
This probably isn't the time for your rattiest pair of panties. Wear lingerie you don't mind showing your friends as you try on different outfits or squeeze into dressing rooms together. If you plan on buying something and you need to be somewhat serious about trying on clothes, wear the type of bra you usually wear under blouses and dresses just in case. Wear comfortable sandals with a heel. Don't forget hair and makeup.
Document the adventure
Back in the day, it was pretty hard to sneak a camera into a dressing room. (You took pictures of yourself in fancy dresses, right?) With smart phones taking better pictures than most point and shoot cameras, it's now easy to document your shopping adventure. Better yet, you can bring your internet friends with you by using networks like Instagram and Twitter to crowd source opinions on the size of your butt in those jeans.
Budget and behave
You don't have to stick to trying on unreasonable clothes options on your fashion date. Give yourself a budget to pick up one or two items, like those shoes your girlfriends said you absolutely had to get. While embracing your inner teen, tune into your adult sensibilities by keeping dressing rooms clean when you're finished trying on clothes. We won't fault you for hitting the wine bar near Macy's during lunch as long as you don't get kicked out of the dressing room afterwards.
