Since I’ve read this question a couple of times I thought I’d do some quick reference shots. Alasdair stole Ruben’s shirt ;). Depends on the fabric, I’d say. Stiff fabric looks definitely weird, but shirts might work if you don’t mind rolling up the sleeves. Pants work well, they are too long of course, but they can be folded to the inside.
It looks a bit sloppy but ok, I think.
