anyone think thinner lapels and thin (not skinny) ties are not good for a tall slim guy? maybe it exaggerates slimness?
Yes, they do, as do narrow ties. I would opt for a 3 1/2 inch lapel at its' widest point. Also,narrow lapels will look very dated
in the not too distant future. The SF parradigm, for what its' worth, the current bespoke examples from, Steed, NSM, Solito, etc.
all have wider more classical lapels.
Ticket pockets will make the jacket look more informal....
