If there was collar gap in that jacket, it's likely due to the way i was holding my arms for the picture. That said, you're right that it's an issue that comes up as one puts on weight. I think i would leave the top button on the ct shirts unbuttoned as well to make the collar spread more. Can't tell it's unbuttoned with a tie. And yeah, this jacket is definitely starting to get small. The better fitting one got snagged and i need to have the hole rewoven. But the local place has a month wait and my next interview is in Miami. The suit I'm wearing is way too warm for that. So i need to confirm dates before having it rewoven.
