I give my Sims four or five everyday outfits but usually let them choose which one of them they want to wear each day. I really like to change up their hairstyles too. It really bothers me though if their day-to-day hairstyles aren't consistent (for instance, if one day they have bangs and the next day they don't.) I usually just give them one outfit for the other categories though. Tbh I kind of wish that the other categories (except swimwear and sleepwear) didn't exist, and that they would just wear their everyday stuff to special events unless I told them otherwise.
