A bare minimum of 3 (=my wedding ring set) … and more often than not, I’m also wearing 2-3 Disney rings (2 Crislu- white gold Mickey & rose gold Minnie probably 90% of the year); plus a bonus sterling silver ring wrapped in tiny Mickey-inspired gemstones (worn only on Disney trips)
Anywhere from 0 to 3 between the wedding band and other rings I have lying around. I don’t wear any to work. Lost my original engagement ring doing that. Lesson learned.
