You Go To The Costume Store.

You decide that if you want to celebrate Halloween, you needed a costume like everyone else, even though you were close to that age of being an adult. It couldn't hurt to dress up as something, or someone on Halloween again, seeing how that you are too old for Trick, or Treating, so you just wear it for fun.

You arrive in front of the costume store, and park your bicycle, while also grabbing your wallet out of your jacket pocket. You go inside the store, and find that they have a complete variety of costumes from fur suits, skin suits, and even some sexual ones that might be able to set out your inner person. The next question was, which costume will you choose? Which persona will you disguise yourself as on Halloween night, and enjoy yourself further, until something happens?
