the glasses enhance neither of those girl's look. They would be stunning without the glasses. I'm not saying the glasses make them un-hot, but it's unnecessary and if anything slightly decreases not slightly increases their hotness.
Here are a list of Dentist supported female visual enhancements:
makeup
fake breasts if you don't have any
form fitting clothing
regular piercings.. like 2 earrings
Not approved:
stupid glasses
any tat
any hair coloring that doesn't fall into the category of potentially god given.. so if you're a brunette and want to go blonde... fine... but if you want to go purple or something ridiculous, then no.
"punk" clothing
excessive piercings
big fake nails
(more to come)
