(In re-reading the original question, I see that the request may be for the recommendation of a London source for a blazer, rather than a recommendation for a blazer to take to London. Â Perhaps my post might be of some general use) Â Â The db model they sell year-round at Ralph Lauren is beautifully detailed and executed. Â It has some animation and personality--nipped waist, hand stitching along lapel and pocket edges, a mid-weight brushed wool, and a wonderful lapel roll. Â It does feature something like 14 brass buttons, which will send certain forum members into a paroxysm of horror.
What's so horrifying about 14 brass buttons on a DB blazer? I assume you mean that it has a customary 6-2 pattern with 4 buttons on each sleeve. Sounds perfectly normal to me. I know some people don't like brass blazer buttons, but they do kinda traditionally go with blazers, I think.
