I think that it's Tom Ford.
High Street chains are very dialed into the tastes of their demographic. You just need to find something that fits you. Of course, if you walk into a store catering to a very young customer base, you are going to get clothing meant for their body types, and styles that appeal to a large segment of that demographic, at that moment. The clothes are not meant to last more than a couple of seasons. I'd say that you are just going to the wrong stores for your tastes. Stores that are in the high end of the midrange, like Brooks Brothers in the US, often cater to a much more conservative customer base. Or go shop at Polo. Or go shop at J. Crew, even, which offers a very toned down version of trends.
Anyway, this has veered off my original point, which was not to defend "trendy" suits, though I think that the reaction to them is silly. My point was that the comparisons given in the OP are ridiculous.
