I wear what is comfortable! Being in the tropics this is pretty easy to co-ordinate with what is fairly up-to-date! We tend to wear light summery clothes most of the time,which are always available at good prices.
I never ever take the plung and buy new fashion as they come out. For one, everybody else will be wearing the same thing. I can't stand that. I prefer to wear what I have along with new items of clothing that match my persona and will remain fashionable for years to come.
