I don't wear multiple new purchases on the same day. I break them out slowly. So if I buy a new suit and a shirt, I wear the suit with an older shirt, and on the next day I wear the new shirt with an older suit. It helps me "savor" or enjoy the new clothes longer, and it helps me appreciate how each item works with my existing wardrobe. And I think it's weird to come in to work wearing all new clothes.
