Yeah. If I unbutton it I can get it to lie against my chest. Someone in the DB thread mentioned he was having his tailor move the buttons on a coat he has to get the lapel to lie against his chest normally.
It's a used coat at a second hand store but it looks great and fits good otherwise.
The gaping lapel, or what sounds like a gaping lapel, is from not enough room in the chest. Moving the buttons can work, it just decreases the cross-over and may force the non working buttons too close to the working buttons creating a strange phenomenon....especially if you're a little bulkier.
But of course, not easy to visualize without a picture.
