Thanks, all. I think the general consensus is that the outfit with the booties is good but maybe not for this occasion. Amy is right that I will probably feel too self-conscious in it, so more conservative shoes are a better idea. I think I might look around for other shoes, but in case I don't find anything, I will wear my grey slingbacks that I posted above.
Denise, I do have a silver clutch. Good idea to use it to bookend the lighter shoes. However, if the Heed lace jacket works out, I might be wearing that too, which is ink blue.... hmmm. I also do have a big ice blue cashmere shawl, or, you know, I could always get a silver pashmina from the Tibetan store down the street that always has them for $10.
You are right that slingback shoes are much easier for me. Ankle straps are even better but hard to find, especially paired with a 2.5" heel. I have actually fallen flat on my face at a formal event before because of my shoes, and I don't care to repeat that any time soon!
Oooh, Zap, I LOVE the idea of seamed hose! Thank you!
BJ, you reminded me that I meant to go to Zara and try on their shoes. I asked here about them a little while ago and the consensus was they were OK, but inconsistent so I figured I really should go to a store to try.
I did go by my consignment store last week and looked at the shoes but did not find anything that worked.
