3 events, one dress? could it work?

would this dress link in blue be appropriate for a formal even, a christening and to wear to court?

the reason I'm asking is because I have all 3 of these in November with in a week and I can't afford to buy each an outfit of their own.

so is it appropriate and what would you accessorize with it and wear your hair for each ?

btw. I have long blond and brown layered hair.
