Not suits. The legs are too slim. You could try the Havana or Napoli separates and get trousers one size larger than the accompanying jacket. In Jackets you may have luck with the Havana.
The jackets won't work if you have a large midsection though. Only if most of your, er, extra, weight is below or above your waist.
+1. I do Olympic lifting and had to start purchasing separates due to my quads. I almost exclusively use SuSu for jackets, I find that all of the jackets work pretty well for my bulky-ish upper body, but the Washington jackets are definitely snug against my arms and lats.
If you are a really difficult fit, I'd consider MTM. I've heard great things about Kent Wang, I'm planning on trying him out when I'm financially able.
