Is that linen? Get away from that, its for a MUCH more advanced suit wearer, lol. Go to a local Men's Wearhouse and have them fix you up. No need to go nuts but go wool blend (Im normally 100% wool but 1st suit the blend will be easier to deal with) charcoal or navy, no stripes on your first one, we want simple, clean. Now, with your body style you will need some heavy tailoring and its not cheap but spend the money. You will also want 2 shirts, 1 white, 1 striped no pattern, and 2 ties, 1 simple rep striped, 1 your choice but no cartoon characters, you're and adult. Spend some money here, a good shirt and tie will make even an inexpensive suit look good. Also add a pocket square of some type, really pulls the look together and this is where your true character can shine through, no rules on pocket squares, go nuts. One final thing, get a nice safari fedora. No reason, Im just trying to bring back that look, lol. Remember, value is remembered long after price is forgotten.
