Will my eyebrows grow back?

I plucked my eyebrows pretty thin (well thin for me, i have pretty thick eyebrows) about a month ago, and my eyebrows still aren't all the way grown back. and the worst part is that i have banquet in 2 weeks and my eyebrows look horrible! they sort of grew back in patches. is this normal? and what do you recommend doing to make them look thicker for my athletics banquet?
