It is interesting that iGents have adapted their own personal rule in deciding whether to keep pockets sewn shut or not on RTW jackets. Kind of like Lamarckian evolution:'seems to make sense but ultimately it is wrong.
Pockets are meant to be functional. Full stop.
When you receive your bespoke jacket, nothing is sewn shut unless you asked for it.
Imagine the poor RTW jacket, put on display like a cheap whore to be ogled and pawed by countless iGents.
It needs to look its best to attract the iGent whilst up on display on the mannequin.
It needs to look its best once it is tried on and cast aside after 4 minutes of self-modelling in the dingy dressing room or out under the fluorescent lights where Vincent, your sales associate tries to talk you into the 58L because the are out of 42S.
It needed to look its best when
Chorn
was still wearing RTW and wanted to thrust his giant fists deep inside of those soft pockets to practice fit poses.
Sewn shut to maintain shape for display until sold. Not sewn shut because Luigi Vercotti, or Kam Fong as Chin Ho, master tailors for their respective houses believed pockets must remained sealed to maximize and enhance drape.
So just like Lamarck's stubby-necked giraffe with delusions of grandeur to eat at an elevated level, so too did iGents formulate a theory of the pure sex of the occluded pocket.
Now what about that bit of basting on the shoulder, hmm? That, I believe has a structural function, no? But then again, the world is only a couple of thousand years old, climate change is solely of anthropomorphic origin, and Seinfeld was funny.
