Cuffinks?

[Bugbear]

Nope, I didn't find a description of the shirt I have at either of those links. Although, that first link came close..., but it didn't say it had the vertically pinstriped fabric on the sides of the front and the french opening flap thing.
I'm sure someone on the forum knows what this is.

For some reason, I seem to remember Dean Martin wearing a shirt like the one I'm asking about... And I think it might have been with a regular tie, but I don't remember so well. That probably doesn't help... Probably makes it worse...
