Hi I'm new here. At age 49, I'm (for whatever reason!) really starting to get into dressing nicely. I've bought two suits in the last 6 months and had them tailored to where they fit me pretty darned good, loving 'suit culture!' :)
I think your suit does look a little big and roomy, but like someone else said, you probably look better than 90% of American men I see as I travel through airports.
It looks like to me it could use a little tailoring in the midriff area to have it follow your natural body contours... personally I think that would make a big difference. Someone else felt the lapel was a bit thin but I personally like them that width. That's obviously just a preference thing.
Overall I think you look nice in that suit. When you go for your next one, maybe just take it down a size and see how you feel about your looks in it.
