Nightcrawler (Rule 63)

I think this lady did an incredible job taking an iconic male character and keeping one of the most endearing sides of his personality - the swashbuckler - and made it work as a feminine character. Her make-up (notice the chin and eyes) and streaking her hair with dark blue color works wonderfully. This is one of the elements I love so much about cosplay, taking a well-known and recognizable character and still add in individual flourishes and make it your own. Brava!
