Please help! Haven't been to London for years but I'm due to meet an old friend who I haven't seen for eons for lunch in London. He's chosen the Clermont Hotel near Charing Cross station. I have no idea what to wear and normally live in jeans and jumpers. My idea of smart casual is a jersey dress, thick tights and ankle boots but not sure this attire would fit the bill. The dress code seems to be smart casual/elegant. Please help I'm about as far as you can get from elegant and don't think I own anything that would fit the bill. For context I'm size a 16/18 and apple shaped [and over 70 if you think that is relevant in terms of choosing something suitable.] I don't want to spend a fortune but if anyone's had lunch at the Platform 7 restaurant please can you tell what would be suitable attire for this?. Thanks very much!
