What makeup should I wear with my 50s dress?

It's my sister's confirmation tomorrow and I'm wearing a very dressy black and white polk-a-dot poofy 40s/50s dress. I'm kind of afraid i'ts a bit over the top but anyway....... I'm just wondering makeup would suit? I'm wearing my hair up in a loose elegent grecian style. I'm kind of going for that classic old look, a bit like rachel mcadams in the notebook etc. Any suggestions?
