I'm aware of the website. While it is generally very good, it's not perfect, and reflects the iGent bias against notch lapels, despite hosting things like this ad from 1929:If you want to avoid notch lapels, fine. I'd even argue that it's indeed wise to do so, considering the preponderance of shitty notch lapeled rentals. But the idea that the classic rules held them to be incorrect, or that they didn't exist- it's crap. A modern invention.
