I came down from 250 to 166 now. 39 chest, 34 waist. 5-8 to 5-7. I didn't think that 'slim' would work for me with my 66 yr old stomach. Just got a Banana Republic slim fit linen shirt (M) and it fits fine. May try a dress shirt next (15.5 x 33). Been meaning to try a BB Regent slim as suggested. I like the Nordstrum Trad fit.
