We're going gentle walking in England for 4 days. I literally have nothing to wear!
I've bought some waterproof trainers and a waterproof jacket but apart from then I don't actually own anything practical 
.
I can sort out t-shirts/comfy tops but I am completely stumped for trousers/bottoms. I'm 5'3" with massive thighs and a big bum. I'm a size 16/18 and hate anything tight on my thighs. I'd need full length and definately nothing fitted/tapered/skinny.
Oh and I doubt I'll wear them again so need to ne cheap and cheerful.
Help! Please?
