Help sitting on an interview panel tomorrow

[Bondsolon]

Unexpectedly I am sitting on an interview panel tomorrow. The forecast is 28 and the office is air conditioned. I am mid 50s top heavy size 14.
I have 7/8 navy or black Boden trousers. I have a couple of old M@S blouses one geometry purple pink and black and one all kind of blue.
All thoughts welcome.

I would go for whatever is most comfortable and cool tbh. The people you are interviewing are hopefully more focused on their interview than what anyone else is wearing.

I think the navy trousers and patterned blue blouse assuming it matches in are the most professional. Try the blouse with the black trousers too just to see what looks professional and modern but coordinating professional colours are the best. Don't wear a patterned pink top. There may be exceptions industry wise but that would be your best bet
