Eek - I have second interview on Monday- what to wear?

[basildonbond]

I've already worn my interview outfit and the two people who interviewed me in the first round will be on the panel so I can't wear that again.

I mainly work from home at the moment so I don't have an extensive office-ready wardrobe and everything else I've got is too wintery

I'm 52, 5'7", size 12, prefer trousers, never wear high heels

I don't want to spend a fortune but want to get something which will look good. Ideas of outfits/shops very gratefully received

Can you mix and match? Eg if you were wearing a trouser suit get a different top to wear with it? Or different accessories?
Or perhaps a dress to go with a jacket you have? Sainsburys tu generally have some ok work wear if you're on a budget.

Can't you just wear the same thing again? I've just had a second interview and did that (got the job too!)

I think it's accepted that people have an interview outfit that they trot out. I can't see it being the difference between getting the job and not tbh.
