According to Prose Edda, Thor has indulged in a little cross dressing at Loki's insistence, if that helps.
Hmmm, if I can chip in a few theories here:
* You've done a fair amount of acting in the past and as a result have good control over expression and body language.
* You have a slim build, which helps as well.
* The glasses and long luxurious hair thing as a combo lots of people find really cute in a girl.
* You also seem to have an unnaturally good eye for picking out outfits that work well with your bodyshape - possibly another side benefit from acting?
