Hahaha oops, sorry to freak you out. I put my furry suit and socks and wetsocks on, then my wellies, then put my oversuit on, with the wellies on my feet. Then I put my kneepads and armbands on.
I'm not really sure why I do it this way!
I've got a yellow oversuit - the legs are fairly wide so maybe that has something to do with it, if most people don't wear yellow?
I don't like getting mucky (I know), so it probably started so that I could get my wellies on sooner and not get sheep poo and soil on my socks.
And, until my latest pair (when I FINALLY found size 5/6 Dunlop wellies that are not for children, courtesy of the shop in Lochcarron) my wellies were pretty tight on my calves, so it was a struggle to hitch up my oversuit leg enough to pull them on. That's also a factor. Now I've got grown-up wellies perhaps I should revert to the more conventional approach?
