Hey, Tam, can you get the lowdown on this ball from others who've been there in the past, to get a sense of what's considered appropriate?
Since it's a work function, it seems important to maintain some kind of professional stance -- as opposed to, say, if you were going to a fancy wedding or the Oscars.
Here are my thoughts on the dress itself. There is no doubt it's hot on you, but in this case I'm wondering if it might be a little *too* hot? [Congratulations, Tam --- you're too hot. In the grand scheme of problems, not a bad one to have ;) ] Being short, strapless, and a siren color, it might be over the top for a work event. I would suggest a dress that incorporates one of those elements rather than all three.
As far as dressing it down, I will be interested to hear Angie's view but to my eye this dress seems too far down the formal spectrum to balance out with denim, if that makes sense.
Having said all that, formal wear is way out of my league and will now cede the floor to others with more experience. Shiny - this seems like something you would know about?
