i need a fast tan for prom?

my senior prom is in just under 2 months and i'd like to get a decent tan to go with my ivory dress. i am pretty fair skinned and don't usually tan well outside. i signed up at a tanning salon which was working for a few months but they closed down and i'd rather not do any radiation again. normally i embrace my white-ness but this is prom so it's kind of different. what are some ways to get a nice tan in under 2 months?
