Third is fit, fit is a personal preference based on what your size is, how tight you want your panties, and which panty types/styles fit and feel best on you. I recommend trying each of the recommended panty types in your size(s), so you are able to decide what you like best. As of now, my personal favorite brief panty is the Princess Juliet Panty, and my personal favorite thong panty is the Princess Juliet Thong Panty (links are included below).
