Excerpts I found interesting:
Anderson & Sheppard had a 2012 turnover of 4 million pounds and growth has been over 13 percent every year since 2009. A number of other houses on Savile Row have also enjoyed over 10 percent growth in recent years with total revenue for the informal group of suitmakers now estimated to be 30-35 million pounds...
Clothes that were then dismissed as old fashioned, over-priced and going the way of bowler hats, are now the subject of renewed interest reflected in sartorial blogs and forums from India to the United States.
"We've noticed that we get a lot more younger customers coming in. I think that's particularly the result of the internet. There's so much more written about bespoke tailoring now in books, magazines and online," Heywood said.
Chickenfeed in the overall menswear business, of course; about 0.1% of the total - and presumbably high-end only - figure for the total menswear fashion industry of £35 billion that they quote. And I suspect the increase in turnover is actually more down to the increasingly international profile of London's better-off residents and general growth in emerging markets, plus I notice that the theoretical asking price for a suit tends to go up by at least a good chunk of that overall turnover growth rate each year. So I doubt that the blog/forum effect is quite that big.
But still, interesting to see some figures.
