What to Hairdo for NYE

Today the question that plagues me is what to do with my hair on New Year's Eve. I'm attending a party with my husband where I'm sure to know few people. This relative anonymity will allow me substantial latitude when crafting my party going outfit. Will it be a vintage dress in rich brocade or a simple black number with a chunky choker? As always my fashion decision begins with my hairstyle. I'm thinking of heading to Ulta and getting a set of hot rollers or a giant curling iron. Big wavy hair would be an excellent accessory for the evening and I could contrast the mane with a very simple dress. However, my hair is rather thick and straight and uniquely resistant to curling. On the other hand, an up do would be so elegant with a long gown and satin heels. But, the amount of pins and spray will undoubtedly give me a headache before I leave the house. Maybe I'll just mess it up for that "bed head" look and wear a slip dress. However, I'd rather not suffer for beauty and shiver, underdressed, in the cold. So many choices, so little time... The only thing I want to avoid is overspending on an outfit for one party. Nothing's worse than spending a lot on something you'll only wear once. (I guess the garnet red taffeta dress is out).
