What distinguishes a date from a platonic hangout with an acquaintance?

Assuming a female acquaintance asks you out and you say yes. It seems like labels and intentions get more blurry when going out with an acquaintance you’ve known from the same clubs/church/groups as you’re in, because there is just enough platonic connection and the right amount of mystery for a romantic potential. It is also different from asking a random stranger out or online dating because physical attraction is already implied by wanting to spend time with them without really knowing who they are.
