party outfit advice needed!

[daftbesom]

Hi all - I am going to a weeknight dinner and entertainment in a backwater hotel (not posh, not scummy), with about 50 people, mostly of the older persuasion, no partners. Thing is I haven't a clue what to wear.

Saw a photo of last year's bash and everyone seems to be wearing separates of the middle-aged variety. I don't really have anything like that.

I have:

grey silk button-through dress - a bit low-cut;
floral dress - a bit low-cut;
50s style polka dot shirt-waister type dress.

What do you think?

Grey silk plus camisole

Topshop, of all places!

love this/these

Thanks both - I wore the grey and felt just right in it.

Love the camisoles, MrsLettuce - although I didn't wear one this time round, it was not as low-cut as all that! Wore a big silver necklace instead.
