I hear more often than not how out of control bachelorette parties get these days. Weather your flying to a tropical destination (if you can afford it- more power to you), or are spending a fortune on limos, hotel rooms, dinner and drinks, etc- be not afraid. There are some cost effective, totally fun bachelorette parties to be had. Bridesmaids just need to get a bit more creative!! =)
Lingerie Party: This is a concept I am totally for. If you live in New York City, there are tons of lingerie boutiques that would love to have you and your girlfriends there for a private shopping session. All you need to do is ask the question. Shopping for lingerie, while sipping chilled cocktails and snacking on finger foods sounds like a perfect night to me!!
If you don't live in the city, see if any local stores will do the same. They may even be able to travel to your house!
Spa Party: You would be surprised at how many spa's will close the entire store for you and your girls (given you have more than just you and your sister!). You can bring in your own beverages and appetizers and get pampered for hours on end. Mani/pedi's, massages, lounging in a robe an slippers. Does it get better than that?
Dinner and Drinks: If your looking to get a little bit rowdy, we understand. Depending on how many girls you are traveling with, instead of getting a limo- having an SUV for the evening tends to be cheaper. Also, choose a place that you can have dinner at and have a wild time after. There are a zillion places that you can go to for dinner that turns into a lounge/bar scene later in the evening. A lot of the time when you eat and drink there (and making friends with the waiter and bartender never hurt anyone) they will pick up a few of your drinks, maybe even an appetizer. And if you play "this is my bachelorette party" card, you are golden.
