Another good costume resource is the Goodwill or Salvation Army stores where clothing is cheap and you are likely to find out-of-style or retro items that are perfect for a costume. Please pick something that makes you look pretty and feminine and plays up your assets. You can look hot even if you are a vampire!
4. Costumes can rekindle the playfulness of Halloween. For my dating coaching clients, I recommend they find a way to get that child-like playfulness about Halloween back and to let themselves have fun with it. The more relaxed you are, the friendlier you'll be. Stop letting those goblins and ghouls of a "why bother" attitude or "that's just for kids" outlook get in the way of meeting men. Halloween parties are big with singles groups.
To find one in your area, check out www.meetup.com or Google the words "singles + Halloween + your zip code" in quotes and see what comes up. Then put on a costume or even a simple mask and go!
