Yes, yes, yes. For basics, go with 120s or 130s tops. I like the VBC fabrics a lot, BTW, Retro. Don't go too fine a fabric, or too shiny. Depending on your climate, a nice brushed 3 season fabric may be the way to go. But I agree with Retro that construction does improve appearance -- a good fabric can be ruined by poor construction. So, go full canvas even if that means choosing a less expensive fabric. Though you might not be able to tell a canvas suit by sight yet, you will soon be able to. In addition, what makes a plain suit stand out besides construction is the cut. A nice style -- good button stance, modern lapel notches, good waist suppression (this is more a job for the alterations man/woman, to be honest), high armholes, nice vent (I prefer double) -- will take you far above the crowd.
