First off, church Sunday. Everyone gets dressed in their very fanciest fancy clothes and parades around at church. While I can fully appreciate the symbolism here, really, you don't have to go out and buy some super fancy clothes. Really. No one else will know if that pretty dress was secondhand or off clearance rack and no one cares. Seriously. God does not care what clothes you wear. I'm not any sort of expert on theology, but of this I'm pretty darn certain. What with natural disasters and nuclear disasters and moral disasters and everything else going on in the world, I'm fairly sure that whether you are wearing something brand spanking new is not even on God's radar as something to note down to decide on whether he invites you over for eternal tea. So get something that looks nice if you must, white is a good symbolic color if that's what you're looking for in Easter Sunday clothes, but get it at a price you are comfortable with.
So our complete family Easter celebration for 3 kids (the oldest is at his dad's for Easter) and usually 4 adults is about $30-40. I feel like that number is high and I might try to bring it down this year, but apparently, the average family spends way over $100, not including Easter clothes, so I guess I'm doing good!
