Help me on prom hair! Need by Saturday!!!?

Okay, so our theme is a masquerade. I really don't care about following the them too much. No one I know really is.

Well, my hair is a dark blonde, layered, and just barely past my shoulders.

My dress is strapless. It's dark purple (k-state wildcats purple, to be exact) and it's trumpet/mermaid style. Those that don't know, that means it hugs my body until between the knees and hip area and then it fans out. I know when I get my hair done, they might have some ideas but just in case, I don't want to leave the stylist hanging without a clue of what I want done or what should be done.

I do want it to be an all updo, unless you have a better idea of an all down or half up, etc. And I don't want it to be all back, I like a little bangs showing because I feel awward when it's all back.

I know I've put on a lot of requirements. . . But I also have a regional band solo/ensemble festival that day. So I'm getting my hair done pretty early. If you have any ideas of something that I could easily manage or fix throughout the day, that'd be swell!

Okay, any and all comments are appreciated! Please link pictures!!!!
