That's not what I mean. The cut isn't the same as a 14th c. design. I think Sir Brian is right about how it looks like a copy (though I think he means Revival Martial Arts, not Revival Clothing, as the former has the bad design and the latter has an excellent design). The way the shoulders are sloped it means that for some builds (such as my own) you'll have a gap above the shoulders, making it bunch up when you lift your arms even though the waist doesn't lift.
Unfortunately, the grand assiette sleeves are tricky, and that's why the good ones are so expensive, and the cheaper ones fit in a funny way.
