Obviously, you should practice standard hygiene. That means clean clothes, brushed teeth, no ear wax hanging outta yer ear, no bushy nosehairs sticking out, trim beard/goat/stash, trim nails, skin lotion for smooth hands, etc...
But, while I agree that alotta women judge a guy based upon his clothes, beware these types cuz they judge you before they know you. Provided you keep yourself well-groomed, what kinda clothes you wear (as long as they are in good shape) really doesn't matter, does it?
Actually, the kind of shoes or clothes a guy wears is indicative of how much money he makes. So watch out for gold-digging skanks! She should only judge you realistically once she gets to know you.
Any woman that judges me by my shoes or whatever clothes I wear can kiss my a$$.
Find a woman that judges you fairly - everybody else is a waste of your time.
