Thanks for that MF. I'd be interested in seeing that vid. Also if anyone has experiences with any of the knits listed, pleased to get feedback and recommendations. On re-rolling. The worry is that the canvas or structure in the lapel has been rolled in a way that fights the new roll or reveals itself as a small perturbation in the lapel (i.e. where it originally rolled). I'm fine on the one that I had my tailor convert, but the jacket is fighting it in its small way. The other issue to consider is that the button hole will not always be made to show as a 3/2. That is, the sewing on the inside part of the hole might be different, less clean. This is true on my jacket (it's a second-hand made in USA Burberry London that I picked in a thrift store). Still, if Cox's was bespoke and has hand sewn button holes, maybe not a problem? Have others here tried?
