Went to M&S today and tried a couple of suits on, turns out I'm a 36 (whereas my previous suit from Burton was a 38) but then again sizes do change with different companies. Anyway there were only a few suits in M&S that sized 36, I had a look around Next but they didn't seem to display the material the suits were made from. I checked out Slaters and found this, wondering on your thoughts, pay £20 over my budget for a 3 piece suit that's 80% wool, it seems like a good deal but I haven't had previous experience with Lambretta...
