Wrinkles under the collar are a balance issue, not sure how severe it is but it could be fixed if the tailor knows what he is doing. I would be more concerned with a high button stance on that suit, it is not doing you any favors. All coats from HY have high button stance, not sure why he does them that way? Maybe he models himself and could be a shorter guy.
I like me some high buttoning points (srs)
They just feel a lot more comfortable to me than lower ones. Maybe Holdfast can make something of the fact that I like the feeling of my chest wrapped in cloth.
