Take the same waistcoat and put it on the woman and ..... well it's not a great look really
I'm sure "a good fit" was probably the last thing on London Underground's mind when they designed these waistcoats and they're probably "one size fits all" or S, M, L, XL and XXL. This did look rather unfortunate on this woman, particurlarly the way it seemed to balloon out at the bottom. It also clashes with the Tube Blue sweater that she's wearing underneath. But then, I spose flourescent orange is hardly going to blend with anything!
