Day-to-day, my wife mostly wears bikini-style panties. Most of hers are Victoria's Secret branded, which she acquires at their semi-annual sale.
She's not a fan of thongs, t-back styles, or G-strings, and only rarely wears them, usually as part of a lingerie ensemble for an encounter if she is so inclined.
No "granny panties," and she doesn't feel that boy-shorts flatter her.
For encounters, it runs mostly to no panties at all, where she will wear stockings (sometimes stay-ups, sometimes with a garter) or sheer, seamless pantyhose, or crotchless bikini-style panties.
