It's interesting that no one here finds them to work; I never have either.
I think it's the wide neck which I don't like - it strikes me as feminine. Indeed, my daughter wears them, and the look fine.
It may just be that you have to have that kind of Gallic peasant physique - short, stocky (but not fat), maybe a receding hairline. I remember a childhood friend of mine - French - whose father had grown up in French fishing villages, and he was maybe 5'4", tops, and built like a cube, about as wide as he was tall. He was immensely strong, probably the strongest man I've ever known (and *real* strength, not gym-culture "how much can you press"... this was "haul the catch from the ocean and don't get your finger caught in the net or you'll lose it" strength). He could have worn one and it would have worked (although he only wore three piece suits, 24/7/365 - he took us to Disney World once, in July, and wore a suit. He was a beast!)
