What do you wear in the garden?

I can't abide the feeling of jeans on the backs of my knees when I'm kneeling, it just  itches and irritates like mad, so I tend to wear leggings with baggy joggers over the top when it's cold. Flattering it isn't   but I don't care. Luckily shorts & a vest are enough for most of the summer. 
Shoes are proper trainers or stout boots because my feet are painful due to RA, although I might potter in flip flops in the summer.
I have a friend who is obsessed with getting a tan so gardens in a bikini from the moment the sun comes out, sometimes with wellies...
