Color Palette--Decisions, Decisions

We are having the hardest time picking a color palette. I would love some input from you lovely ladies!

Option A: black, purple, orange.
Traditional Halloween colors. I would want a dark purple and burnt orange to give it a more elegant feel. Problem: I'm having a hard time deciding if purple and orange really look all that good together and FH thinks it's too many dark colors. I was thinking the guys in pin stripe suits with burnt orange accents, the ladies in long, dark purple dresses. My dress is long and lacy and I could do a dark purple sash with lots of orange flowers. Sort of a "gothic elegance" look, maybe bring in some damask.

Option B: brown, lavender and plum.
A softer look, I like this one a lot. Problem: I'm in a huge purple phase right now but maybe this is too much purple. Although I would've never considered before, I recently saw an ad for a suit in a wedding magazine in which the guy was wearing a black suit with a brown vest and tie. It looked pretty good. I could even do a brown vest with a dark purple tie, the ladies in dark purple dresses and my sash the same, a mix of dark and light purple flowers.

Option C: brown, burnt orange and purple.
I think this has a very Fall feel to it. Problem: Again, I'm not sure about orange and purple together but I keep thinking it would look fine. Guys in suits with brown and orange accents, purple boutonnieres. Ladies in purple or burnt orange dresses. Flowers in orange and purples.

So, what do you think?
