This suit is from US ebay. I bought from Oxxford clothes on the US ebay already this suit, 2 sports coats and one SB marine blazer. The quality is undoubtedly something of the best you can get in RTW. Prices are also very nice compared to brands like Kiton, Brioni, ISAIA etc.
I wear some of my "real" cuffs tomorrow, I promise.
I think silk knots could be ok with more casual items - I don't think they work well with a suit this nice. It deserves to be complemented well.
