If you are interested in American trad menswear, do yourself a favor and sign up for the O'Connell's "Clothes Call" newsletter. I enjoy reading the occasional interview with one of their suppliers.
Recently, they featured an interviews with Chris and Annette Blackmore, the founders of Chrysalis Clothes, a manufacturer of English RTW outerwear (field coats, sports/shooting coats, town and country outerwear). One learns for instance that the export markets makes up 50 percent of sales, with the largest markets in the US, Germany, Benelux and Scandinavia. The photo above shows their Beaufort coat.
In another issue, O'Connells interviewed Jules Hertling of Hertling Trouser located in Brooklyn, NY. Founded in 1925, the company employs 40 workers (cutters, sewers, pressers) and produces 200 pairs of trousers per day. Turnaround time for a pair of trousers is 10 days. Their production is split 50/50 between pleat v. plain front trousers. A Hertling trouser features a split waist, one or two-piece curtain, pockets attached to the trouser interior, 8 belt loops (instead of the usual 6 or 7). The photo above shows a Prunelle doeskin-finish Hertling trouser in medium grey.
