+1used to be tiffany beads, now pearl studs. Boring, i know, but so versatile!

I think studs are best for gym-to-cocktail endeavors. Or very small hoops that won't catch on anything at the gym. I would say small inside out diamond hoops.
Vca alhambra studs in the sweet or vintage lines would be great for the day to night switch. The small frivole stud is classic, too.
