Costumes at bachelorette parties are always a good idea. Pink wigs, feather boas, wedding veils and oversized sunglasses are all fun, but you could also go for something more bold and elaborate. To really get in the mood, begin the night at a professional portrait studio for a picture of the group in costume. There are plenty of themes to choose from: lady pirates, cowgirls and the always-timeless mashup of 1980s Madonna looks.
After the photo shoot, leave the costumes on and go out on the town. If you're the maid of honor, set up a picture scavenger hunt as you barhop. You can even hire professional party planners who can run your scavenger hunt, complete with elaborate puzzles and field agents to meet at each location during the night.
