Can I wear a wedding gown even though I am still single?

Of course! Make a big event out of it, have an elaborate ceremony and throw a huge reception afterwards, it'll be awesome!

You can do anything you want as long as it is legal. Put on the gown, take pictures. Post em everywhere. Make your friends think they missed your wedding. (Friend: "When did you get married?" You: "Last weekend. Didn't you get my invitation?") It will drive them crazy.

Of course you can, but it's hardly an original or fresh idea. Wedding blogs do this every single day of the week. It's called a styled shoot.
