If you want reasonably priced suits "off the peg" i suggest Pierre Cardin in city centre mall. They have Pierre Cardin, Dunhill, Daniel Hector etc etc. I think the stuff is stitched in Syria but its not fake and well made. They will also alter the suit to your requirements. They always have 75% off!!
