Thank you, it is Vyella. I really like the brand for this type of shirt. The ones with wool in the fabric are fantastic for chilly days. Seeing it in the picture reminds me it needs a visit to the tailor. Usually I am wearing a vest or jacket.
For those confused I should have been better on my post. I was going to a Halloween party as a British shooter. Very lazy of me, just opened the closet but hey, I was comfortable which is more than I can say for my pal in the Captain America get up.
