Dh's work have issued the dreaded Christmas party invitation which includes partners and dh is new to the firm and thinks we should attend. The dress code is posh frocks and masks. He works for one of the big accountancy firms and is fairly senior, if that makes any difference.
I need help to decipher the dress code, I haven't been to a black tie event in 20 years and I have no idea how formal these things are now. Oh and any pointers and links to posh frocks and masks would be really helpful too. I'm size 10-12, hourglass, 5ft 8.
