The picture doesn't seem to work on my computer so I googled "new france kit" and this beauty caught my eye further down the page. Never seen this before:
I believe it is a take on the traditional Brêton shirt which I am reliably informed by a very metrosexual friend of mine is so this season.
Either way, I think it's perfectly acceptable, said with a Gallic shrug. Perhaps England could drawn in our culture in the same way...hey, Morris dancers wear white shirts, now there's an idea.
Thing is, it'd look great were it not for the stereotype it reinforces. Incidentally, the pic didn't load for me either, I had to google it. You might want to consider a different image store.
