Women's Halloween costumes...
#1 99% of what I've seen available are "naughty" costumes. I do not want to dress up like a "Naughty" cop, nun, fairy, cat, pirate woman, Little Red Riding Hood, or any other Disney princess with a skirt short enough to flash my private parts.
#2 Even if I would wear any of the above, they are all labeled "one size fits most", but should be labeled "fits up to a size 2"
#3 Men's costumes might work, but they are much too long and mostly have mask (mask are a big no no for me).
