From what I see- there both is and isn't as much pressure-
Personally, I feel as though society and industry tends to place heavy emphasis on guys looking alright for girls and girls looking alright for guys and guys looking alright for guys... But there doesn't seem to be the same social boundary between women. Of course there are exceptions, and there is that need to look pretty/beautiful/sexy... but I dunno.

I'm probably not explaining this very well. ^^u
