I would never consider a few months old clothes "old"
I prefer a neutral, classic style, so I don't need to care much about the fashion. For everyday use I choose comfortable outfit, often from trekking stores - the advantage of working in a non-dress-code profession - and use them until they are totally worn out. There are styles I like more than others but I would never give up comfort for style.
For formal ocasions I keep in my wardrobe the most universal, classic and fitting to everything items I could find.
I can imagine that one can love the style and fashion but my preference is just not to be bothered by what I wear
