[Closed] what should I wear? posh restaurant content.....

Lucky me, I've been gifted lunch at Le Gavroche for some work I did a while ago.

Dress code is quite formal, obvious stuff like no shorts or trainers, and men must wear jackets. It also says that smart jeans with a jacket are OK.

Obvious choice is to wear a suit, but the issue is that I currently only have one (lost too much weight and my others don't fit) and it's not a cheap suit. And I'm making a bit of a day of it so don't want to be out in my best suit for 15 hours with potential for it to get covered in beer later.

I'll admit, I'm a bit nervous as while I'm looking forward to it I am also a bit intimidated by the idea of Michelin 2* formal dining, so don't want to stand out for the wrong reasons - i can accept 'ooh, he looks smart' but not the other way round. Anyone been, any comment?
