This is what happens when your 4 year old goes to nursery, indulges in water play and is then encouraged to dress himself in his spare clothes. Yes, he looks like he is wearing some sort of trouser/skirt/cape combo, but, in fact, he is just wearing his joggers inside out.
P.S. My feet really shouldn’t be part of this photo but now that I have uploaded it, I cannot be bothered to go back and crop it and do it all again. I am comfortable enough with my feet and taste in socks to put them out there.
