Help accessorising black dress for a ball?

[BooBooGlass]

Please
I have a ball to go to next weekend and have managed to get a fabulous full length vintage black dress. It's strapless, quite close fitting and has a slight bustle at the back (much nicer than it sounds I promise). The problem is that aside from the sit down dinner and dancing, a fair bit of the entertainment is outside and I risk freezing my norks off. I have a very nicely cut full length black coat to wear, but I think I need a shrug of some sort to cover my shoulders. I'm a size 10 but have ridiculously narrow shoulders so most things on me look like they were cut for a man.
I also need help with jewellery. The dress is very simple so I'm not sure wether to keep to some understated earrings or go for a big statement necklace? Am 27 but have a frustratingly young looking face (not a boast, it gets so wearing getting ID'd buying wine and looked up and down while carting my 2 dc around) so don't want to look like a little girl dressed in her mummys clothes iyswim

Size 10 and baby-faced after 2DCs? Lucky you, I say :)

The dress does sound lovely and I would go for something delicate with a vintage vibe - how about pearls? I'm imagining a lovely Audrey Hepburn vibe, which brings me to this shrug. Is that more or less what you'd like?

Ooo those fur shrugs are spot on. But way more than I wanted to pay really. The dress cost less than twenty quid! I love the Warehouse jewellery, had been unimpressed by my mooch around Monsoon earlier. Is fur too ott though?

Of course fur is OTT, but you are dressing up, aren't you? :)

Cheaper alternatives:
shrug 1
shrug 2
shrug 3 - I think I like this one best from this ebay selection.
