It is human nature and more specifically that of men that they are attracted to sexy women or sexily dressed women.
Otherwise, why would you have topless bars and nude bars and porn movies?
And of course some men cannot control their desires (due to their mental fault) and the begin to harass women.
So, sexily dressed women do attract the attention of men and may have a cause in the increase in sexually related crimes on women. Having said that, men ought to be able to control their actions. Women dressing sexily is a separate issue from men raping women. However, dressing does play a major role in causing men to be more sexually alert and consequently may play a role in criminal acts.
