Dresses for appointments?

Okay.. might sound silly, but do anyone wear dresses for their dr visits? I never have because my dr just check for the baby’s heartbeat mainly at the checkups and how would that work? Lol either up exposing my panties? Or down showing my bra? (I know she’s seen my vagina but i still feel awkward) .🤔 if soooo, what do you do??
