I am getting new ones since l still have my first pair from five years ago.
l might get rectangular frames because that is the kind of sunglasses that l get. What do you think?

idk l have a round face and l get rimless ones because no shape seems to fit my face right.

Angular narrow eyeglass frames will lengthen the face to make a round face appear more narrow.

yes my cusin has a round face and she has rectangular glasses

Probably a rectangular pair,they look good on most people.
