I ordered PARA 9 - TARTAN TATTERSALL. This Tattersall flannel fabric is really comfortable. In real life this fabric is much more impressive than the website image suggests. It pairs great with tweed.
Strengths
My dimensions with Bivolino are "dialled-in" and new orders arrive very promptly. I have ordered another three of these shirts.
Improvements or suggestions
Less polyester fabric and more choice in quality cloth
