Yeah, the Liverano cut would also require a three-button configuration. The lapel looks too much of a straight line above the button. The top button would break that up a little, with the lapel somewhat rounded.
Thom Sweeney will be perfect for a modern slim cut. Had a navy suit made there. Their prices are below SR, too, while the cutters learned at Maurice Sedwell and others.
Anything I've seen from Boateng looked terrible in my opinion.
