Lol! Being a double agent without a leather jacket isn't easy... maybe he should stick with the tactleneck.The first born will be delivered in two years once conceived. Of course there will be delays due to Korean holidays.
If you're looking at the measurements on shopthefinest.com, the measurements are accurate. Sizing up on dress shirts tend to not work because of the collar sizes. Yes, the body will fit but the collar won't.
The question is if it's appropriate as a business attire. Raf, Hedi, and Yohji's fall more on the fashion/street wear style. In an office setting, I don't think it's ideal unless your office or business deals more on the artsy side (music, film, fashion, or anything like that).
Know your size. Where are you located? Serie Noire started carrying Backlash. It is on the expensive side (by a lot) compared to getting it from Japan. The stores in Japan don't carry the larger sizes so contacting a store there and preordering for a larger size works. Just for reference, I'm a 48 or 50 sometimes depending on the brand and I only fit on a XXL for Backlash (and it's a bit on the tight side still).Or you could visit their newly opened store in LA located...
