In ACNL I typically wear the aviator shades from GracieGrace. I normally don't wear headgear because I always make my hair bright and interesting colours and want that to show but if I do wear headgear, I quite like the DJ cap and the smaller one of the crowns.
Edit - I don't know if this counts or not but I always carry around my zebra umbrella too which I think was from GracieGrace.
