A woman is used to dressing to impress other women - wearing things that other women will be admiring of otherwise she doesn't feel good. That's the same feeling as you get when you see another woman at the same "do" with the same dress as you. Blokes don't really care, they will sling on a pair of jeans and a shirt and be happy if every other bloke is dressed the same. If a woman is interested, regardless of how he is dressed, he must have got it right and will continue to be that way! I couldn't care about matching/new pants so long as your "bits" are clean.
