Definitely appreciate the advice. I did try the R size but my arms were way too long. I did take a look at the separates on the website and given that I am looking for a solid grey suit the only possible option is the napoli dark grey pinstripe which is sold out in my size sadly. I really would like to stay at the 500 range do you guys know of any other options comparable to SS.
You can check out Benjamin suits at eHaberdasher, they have an affiliate threat here on StyleForum: http://www.styleforum.net/t/69315/www-ehaberdasher-com-affiliate-page/2790#post_8133480
Also check out Spier and Mackay - they're based near Toronto, Canada, so prices are in CAD = bonus! Also have an affiliate thread: http://www.styleforum.net/t/383376/spier-mackay-official-affiliate-thread/2205#post_8131683
Both will accommodate requests for larger size pants for their suits (if they have them available).
