He was at Fashion's Night Out to support his girlfriend, one of the designers behind the hot new shoe label, Bionda Castana, which is stocked at Browns. I noticed his suit and how well it fit him thinking to myself, okay, it will probably be from one of the Savile Row tailors but when I asked him I got a surprise: it was from Reiss! BUT and this is the key I think, he had it altered to fit his exact measurements by his tailor.
I think I read recently in a Times article that Carine Roitfeld does the same thing with almost all of the clothes she buys- she has them altered by what she terms her "retoucher" because "nothing is perfect or exactly the right length".
We might not all be able to afford bespoke but spending a little on alterations (sleeve length is a big one for me) can make the world of difference.
