What defines sexy?

What defines sexy?
Is sexy naked? Does sexy require you to show all and sundry every conceivable curve or flab that your body possesses? I'm wondering this particularly because lady's' nowadays especially the ones who must go to every possible party or dance believe that naked is sexy!!! It is such a disconcerting sight to see a woman in a pair of shorts which is obviously too small for her parading about for all to see her 'baddy'.
Then there is the breast/brassiere craze... most women now seem content with their breast brushing their chin because cleavage 'haffi show'. And for those who are not heartily 'blessed' they must wear push-ups which struggle to find and push excessive skin up on their chest. Now don't get me wrong, I believe in the concept of accentuating the positives but when did showing the breast and brassiere become a legitimate part of an outfit?
Sexy is supposed to be tasteful. It is a state of mind in which confidence plays a critical role. Sexy does not need or want anyone to validate it. Sexy is comfortable in the fact that not everyone will like its brand but is certain that whomever is supposed to take notice does and does so unreservedly.
When I was growing up, I was made aware of a statement which promotes the concept that 'less is more'... these women who constantly parade their nakedness need to be told.
If you show a man all he wants to see then there is nothing left to entice him with. Women must begin to understand that men think differently and if he thinks you're easy... he'll take you alright, he will take all he wants from you and then leave you.
Have some pride in yourselves ladies. We are beautiful and strong. We can be sexy but there is no accounting for nakedness. And it's not every style that will suit your body type. An outfit that looks amazing on a size 4 body may not look the same on a size 14... use your head ladies!
