holiday party, blue silk knee length, cap sleeve, dress, need advice on suitable jacket/wrap, what c

[msbv]

Hi,

I just got a blue-green (sort of acqua blue-green) dress in silk (not flowing silk but more of a sturdier silk with lining), knee length dress, cap sleeves. I''ll be wearing this for a christmas party (dinner/dance) in souther california, so not exactly winter weather but evenings can get cold.
could someone recommend a suitable wrap or jacket to go with the dress as well as what color shoes. Also hose or no hose with the shoes. I bought a pair of pretty sandals (black) but am worried that it might be a bit too cold for hose-less sandals...pumps better?

Thanks!
