I know the feeling. I look at that thank god they don't as it would make it hard to not want a pair. To me it's kind of funny that they make such small sizes in work wear as the men who wore it in the past where big guy's like my grandfather's. Men would worked hard for a living and had the size to prove it.
Different here in the UK. It's very hard to find vintage workwear - British or French - in modern sizes. People worked hard but they weren't big in our terms - tough as nails, of course. Bad nutrition, bad working conditions, living conditions...
