men should not wear the following things:
Flip flops
v-necks
tank tops
boat shoes
crocs
tucked in tshirts
Of course, I say this and new boo picked me up for a first date in boat shoes with his tshirt tucked in.
While I can generally tell if I am attracted to someone right off the bat, I have had a lot of times where men have grown on me because of their awesome personalities. Where I will barely even pay attention to their existance, but after knowing them a bit I think they are super hot. So I think it can happen either way. I've also had some very, very attractive men that have bored me to tears to where I knew no amount of pretty would make me interested.
