I live in the UK and we have a lot of groups of disenfranchised lads in our pubs who get largered up and look for people to focus their attention on. The attention they offer is not always the kind that couples want. They get leery and nasty, deliberately trying to cause trouble for a guy who is with a woman in a short skirt.
Their attitude is that a woman who dresses provocatively, and the guy she is with, has no right to complain. Sometimes it is better to dress down a bit be less noticed. Ther are palces where women don't have to worry and places where discretion is the better part of valour in some circumstances.
