Do you think this ranger/adventurer/sheriff costume suits Helena ?
Not really, but all the DOA girls have costumes that don't really suit them. I think the biggest crime to Helena right now is Kokoro and Hitomi have a better ponytail then her.
In one of the concept arts she had back then, Helena was featured in a high ponytail - http://i136.photobucket.com/albums/q164/InoCaryl/DOA3Helenaconcept_zpscc225052.jpg
Who knows if that will be a new hairstyle for her. I prefer seeing her bow get a white lace variant (there are just some outfits that really doesn't fit the black lace bow for me) or if possible, a completely new hairstyle like high ponytailed curls, full-braided hair decorated with flowers, a Marie Antoinette powdered wig hairstyle or loose hair with her old bow. (just like how she was portrayed in her DOA4 ending when she was little).
