Extended, soft shoulders.
Soft canvas construction.
Vertical folds in front of scye.
Looks like drape to me...
Shoulders are soft but not extended. Construction is soft but that is not drape.
As to the folds, there appears to be one on the left side but that's just the bulk of the pocket square pushing the cloth back. The chest is very lean. So lean that when I put my wallet in the inside pocket, it bulges badly.
