Movie id help needed

I am looking for an old movie, in it a woman goes to a resort to find herself a rich husband and pretends to be better off then she actually is. At the resort she meets a millionaire pretending to be poor and romance ensues. Anyone know what it might be called?

Here’s an Elvis movie called Clambake which seems to fit. But I imagine it’s a familiar plot for films.

Gentlemen Prefer Blondes ?
Dirty Rotten Scoundrels/Bedtime Story?

I’m gonna go with Clambake, my mom asked me to track it down, so hopefully its the right one, thanks.

Helps if I read your parameters…never mind…
