What should I wear for lunch in Michelin star pub?

[LadyAntonella]

I have no idea! I don't want to be too dressy as it is a pub but then it's a fancy pants pub so I guess my New Look skinnies and Vans aren't going to look right either!

I'm a size 14 apple. I don't really want to buy anything especially but just after some ideas really.

Thanks!

We've been to many Michelin star places (expensive hobby). DH has worn jeans and a shirt to them all, except in the US where a jacket was required for men.
