I'll just make it brief since it's a little bit of topic.
In terms of handwork both are excellent with Bn you can ask for optional extra handwork. Both have excellent fit as you would expect for bespoke. I like the styling better on my Bn stuff, they do the spalls camicia better than WW Chan.
The guys at Bn are young and very motivated and often travels to Italy to learn more on how to better their craft. Price wise both houses are very similar.
I have gotten great...
