Please help me shop for a funeral outfit

[cathcat]

My dear dad died yesterday. Please help me get an outfit organised for the funeral. It doesn't have to be black. I need shirt or dress and a jacket plus shoes or boots.
I am size 12 and 5 ft 7.
I normally shop at Laura Ashley, M&S, Debenhams and Boden. Our next town has a bigger selection of shops so I could go there.
Please help, the funeral will be very well attended and I want to do my dad proud IYSWIM. TIA

i bought an outfit today from Betty jackson in Debenhams, this with a black knitted top for underneath and a black/v dark grey skirt. have to get shoes but that's fine. thanks to people who helped last night.
