So this is really Foo's domain, but I'm trying to teach myself Photoshop, and this seemed like a good opportunity to do a cut-rate "foof" that would illustrate some fit / style issues.
Here's the before and the after - excuse the sloppy editing. As fun as this is, I'm not going to spend 100 years doing it . . . . Warning: Spoiler! (Click to show)
The colors were too similar, and frankly, the suit color was incompatible with the your skin tone. You would do better to go less khaki, more grey.
I have another suit almost that same color. One of my favorites.
You may be right about the cut and color. I do like khaki, though.
