don the white hat
v. phrase. surrender; lower one's standards. Inspired by Queen Elizabeth's refusal to put on any cowboy hats, feathered headresses, ball caps etc. that are offered but can be used in regard to any clothing item (tuxedo, grad gown) , job, dinner with in-laws etc.

The prom is this weekend. Are you gonna don the white hat?

I'm a gonna go alright but I ain't no white hat donner.

Then you might not get no punch.

I'll tell you who's gonna get no punch and it ain't gonna be you!
