And social status?

Hypergamy (marrying up) is a thing in many cultures.

And then there's always the good ol' standby - sense of humour.

Yeah, if I remember this correctly, studies have shown that a man's level of success effects a woman's determination of how attractive they find him (where the reverse isn't nearly as true. A woman's level of success doesn't affect a man's determination of attractiveness)...

It was years ago when I saw this, and after only a quick search, can't find any studies on exactly this online, but am sure these have been done.
