Thinking the best way to dress yourself is to let someone else decide what is "in" just seems odd to me. But then I dress based on what I like rather than what someone tells me everyone else thinks I should be paying through the nose to wear.
What passes for "fashion sense" for me doesn't necessarily even match, if I'm dressing based on practicality. One day I was out and about and stopped by the church wearing black shorts and a blaze orange sweatshirt. Without even trying I managed to blend winter and summer clothes, and a lower half that kinda disappeared into the background with an upper half that did anything but.
