Thanks so much @Johnsson
, I appreciate the trouble. The lapels look very slim in the photo, but it may be because the waistcoat is lying flat. Do you find they're that slim when you're wearing it, or do they open up a bit?
You're welcome. It's a pretty accurate depiction of their size. The suit has wide lapels, but the waistcoat's are definitely on the slim side. As only a small fraction of them is visible once the jacket is on, I'm not sure the extra bulk of wider lapels would be worthwhile.
