After enjoying a number of fabulous submissions on Flickr, Tumblr and in story comments, we chose the five most creative and charming Halloween costumes of the bunch. Check them out below. You may get an idea for a last-minute costume or see ways to tweak one you already have. Be sure to tell us which one is your favorite -- and feel free to say what you're dressing up as this Halloween.
Congratulations to our winners and a big thank you to all who participated. Happy Halloween from the Mashable team!
