I have a great response to people who dress to feel good. I intensely dislike the expression to dress age appropriate because that ideal is settled on in the minds of those people who have a control issue.
Dress as you like because it is only you who should please you. But saying that I get such a buzz when I see men and women dress in a trendy fashion. Age appropriate or not, I love it.
Even shop assistances are coming to grips with all ages buying clothes in any age shops. I was mingling with the teenager set in one of those trendy clothing boutiques to only be rubbing shoulders with teenagers and grandmothers alike choosing the same fashions.
Fashions are in the mind of the beholder and wear it as it makes you feel and remember to walk with a good deal of attitude.
