MD, I think that the suit itself looks good, but I have two, small criticisms:
1) I would have chosen a different pocked square, either a plain white square, or one that was more muted, with a darker pattern.
2) I think that all suits should be worn with ties and that wearing a three-piece suit, in particular, really demands a tie, rather than an open-necked shirt. The informality of the open collar with no tie clashes with the formality of the suit and waistcoast, to my mind.
Agree re above. Also, the pants appear to be draping in an unusual manner. Is that because of the stance?
