I certainly think that dressing far too young for your age is very unattractive. But you can still look great and be fashionable without looking like mutton dressed as lamb. Besides that, as a 50 year old woman, I wouldn't be seen dead wearing some of the awful fashions youngsters have today! LOL!
As for romance - you're never too old! There is nothing in any rule book anywhere that says you have to stop loving or living just because you get to a certain age. I for one will continue to do what pleases me and to hell with what others - young or old - think.
