To this day I've found that it doesn't matter what a guy looks like if he's really funny. His sense of humor makes him attractive. On the other hand you don't hear men saying 'No she's not pretty but is she ever funny!'
I try not to wear anything I have to fidget with - there's nothing worse than wearing something and pulling down the hem and re-adjusting the top. My pet hate is when girls wear those strapless dresses and spend the whole night yanking them up.
