Judging by what the following ladies are rocking underneath their pants, it appears that regular panties (specifically white) are pretty common and perfectly acceptable…
Thanks. Also worth noting… girls who play softball in college are pretty diligent about wearing tight, white softball pants. However, they’re just as diligent about wearing sliding shorts underneath their pants, which conceal panty lines really well…
Though one can still enjoy a player’s, um… “assets,” the panty preferences of college softball players are a little more unknown, due to the popularity of sliding shorts.
