As I was the one who first commented on Don's trouser width, may I just point out that all I said was that I couldn't help but feel that sometimes they were cut too wide.
A couple of weeks back, Don posted one particular fit where the trousers were cut just a little slimmer, and to me this improved his silhouette.
It was just a gut feeling I had. I'm no expert on menswear, but I have to judge and advise on human proportions on a daily basis in my job, and I have a certain level of confidence in my gut feeling. I have no idea whether my observation contradicted any particular rule.
Don responded quickly, stating that he has a couple of pairs of trousers at the tailor now. It will be really interesting to see the results. I might be proven completely wrong, but either way, I really respect the effort Don puts into his dressing and I hope one day to be able to get to a similar level. Keep up the good work, buddy.
