So I don't really know the reference codes for any of this, but I do know that it has the highest collar band that IS offers, with a 2-button closure. The collar itself is a semi-spread that IIRC has a 3 1/8 inch point, or something close to that. I don't think it was one of the standard options available on the Epaulet site, but it was among the expanded options available through IS. As far as tie space goes, I was told that all of their collars come with 1/8 inch of tie space as standard and that this cannot be modified. I personally don't think that's quite enough, but this is a matter of taste. Some people want the collar to form a triangle where the two sides meet in the center and others want the collar blades to frame the tie on either side but not cover too much of it.
Thanks, interesting to see that. I think the two-button closure probably accounts for the extra space I'm seeing. It was just quite a distinctive collar. I'm a fan of more height (regardless of tie space per se) in non-BD collars. It looks great, in any case!
