As far as fashion, my Dad is professorial. Think sweaters. I have seen him wearing jeans. Once. He has however, dressed my mother brilliantly since the beginning.
Recently he came to me because for years he and my mom (who is also stellar) have purchased some organic wooden toys as gifts for small children, but he can no longer locate them. They were very well priced, made by women in India (I think) and, in his words were "truly wonderful, great to play with, creatively designed, meticulously made, and finished in a manner equaled by few toys or other products". They are a great value (well priced), help people support themselves and are visually and tactilely pleasing. Typically Mom’s the Word does not sell toys. Dad's doing some research. You may see them soon at a Mom's the Word near you. If you do, you'll know- It's a dad thing.
