Do a search on both StyleForum and AskAndy - there have been numerous threads on Brooks made to measure suits, shirts and RTW suits.
Novalis is right of course. But I'd just add very quickly that: after a decade or more of really bad design and quality, Brooks is making some come back. I doubt that the Brethern will ever return to that bastion of understated, high-quality, good-taste at a reasonable price. But the Oxford clothbutton-down shirts (USA-make), repp ties, socks, shoes, and most of the suits are good quality. I was impressed with the 3 button (rolled to two) suits made by Southwick in navy and grey. One of the best deals around for a good quality, reasonably priced traditional suit. (Not to be confused with the Brooks copy that reads "traditional" 3 button -- which isn't at all traditional, at least in the pantheon of Brooks). My only suggestion is to find a Brooks that has tailors who've been working there for a long time. Most of their seasonable items (madras and seersucker) are a disappointment: the quality and style isn't very good.
