i'd say hair. and this is my thought process. if someone has interesting hair, they have some sort of fashion sense. that is a bit turn on for me. usually they know how to present themself, to show off their body. usually have interesting make up, none, or enough to pull off the look. i find myself liking more 'new' and 'interesting' things lately. however one can always tell if someone is just drop dead gorgeous.
