Fleetwood Mac gig, outfit help!

[MaeBug]

Hi wise ones! I'm looking for some help, i was invited last minute to see my favourite band in the world ever... Fleetwood Mac yesterday so have eagerly snapped up the chance, only to remember i haven't been out anywhere more exciting than Tesco for the last 2 years and i don't know what people wear when they're out out! Haha.
I've got a week to shop, i'm a size 10 and walk like a crab in heels...
What would you wear?

I would go smart casual in case I wanted to go to a bar as well so I'd wear skinny black jeans with a pretty cami top, biker jacket & either pointed flats or smart trainers, nice jewellery & a smart crossbody bag for your money make up & phone!

Ooh my favourite band too. Go the full Stevie in scarves and a top hat, release your inner hippie.

I wouldn’t wear heels to a gig, you want to be comfortable, I’d just go jeans, nice top and flat sandals/converse style plimsolls. What do you ideally like to wear?

Definitely don't wear heels or uncomfortable shoes if standing, saw them in Dublin a few years back and they played for a really long time. Like over 3 hours? I was crippled by the end! Amazing gig though, very jealous!
