I am not a huge fan of brown suits generally. Something about them just makes me think they look too rural or informal. This suit, however, is an exception.
I love the contrast of the stripes of the jacket and the checks of the vest. This is a great example of how playing with complimentary patterns can really add an eye-catching element to your standard suit. Here, the colors are the same but the variation in the pattern arrangement gives the outfit a sense of depth and vitality.
Also, check out the bowtie/ascot/scarf. Little twists like this can really pull an outfit together. Taking something like a scarf or handkerchief and tying it around your neck as you would a bowtie gives a brazen edge to an otherwise put-together look.
Lastly, make sure to slick back your hair and look super serious and you will OWN that brown suit.
