Collar gap describes the distance between the jacket collar and the shirt collar on your neck - like in that photo of Tom Ford above. It's most noticeable on photos that are taking at a side angle. The photo you showed doesn't really show a collar gap. It's just small, rather narrow shirt collar with a skinny tie and what seems like a narrow shawl collar. Not necessarily a bad look and I can't really see a collar gap there.
The link you quoted above is interesting, one of the photos used is from Indochino's website. Actually, the collar gap is not that visible on the model for me, but the pulling around the top button is something you will often see on Indochino's models.
Edit: On West's suit there is a collar gap (maybe due to his posture on the pic), but it's not the same as on the photo you posted. It's not the distance between the point of the collar to the lapel, but the space as described above.
Edit 2: What VinnyMac said.
Thanks L. (It's CGFA from RFD here.)
Regarding the Kanye West photo, the lower arrow is pointing to a space between the shirt collar points and the jacket lapel. The photo I posted above of Chace Crawford in the shawl lapel jacket and tiny shirt collar also shows a large space between the shirt collar points and the jacket lapel.
I suppose tiny shirt collars aren't as much of a crime as collar gap, otherwise small shirt collars wouldn't be so prevalent.
In this case, I go back to my second reply in this thread (Post #2989) and claim that I cannot see collar gap in any of the photos I posted EXCEPT for the final photo (the closeup of my torso). The jacket lapel seems to rest nicely on the shirt collar all along (except the last photo of course). Maybe I can direct Indochino to "tighten" up the jacket lapel a bit when I request my remake.
Am I getting the wrong impression? I learned about "collar gap" from the following link: http://putthison.com/post/7215023321/collar-gaps-shoulder-divots-an-explanation
The photo of Kanye West shows what that author is calling "collar gap".
What would be the technical term for the "space between the shirt collar points and jacket lapels"? And is that space a severe issue or is it acceptable?
From that article:
Thanks nautikal. I understand that. I'm not worried about the place where the tie knot goes. I was initially concerned about the space between the blades of the shirt collar and the jacket lapel, of which there is a large void shown in the photo of Chace Crawford in the shawl lapel jacket with tiny shirt collar blades.
