Well, you'll need the suit - if bespoke tailoring is out of the question, then something made-to-measure could work. You're looking for notch lapel with functional boutonniere button, no ticket pocket, no pocket flaps and a cuff in the pants. When you bring it to a tailor, show him this photo - this will let him know you don't want more modern, slim adjustments. A white pocket square gets nestled in your breast pocket.

The shirt and tie are next – you can go button down collar or not. there are several collar styles, search around for the best approximation. The tie pattern will be difficult to match exactly, but you're looking for a dot pattern on brown. A gold tie clip holds the tie in place.

The shoes aren't very detailed, but don't appear to be wingtips, so that leave you something with a cap-toe or something with a plain toe, both in brown of course. With the hat, I really suggest you take a look around a local hat-makers because you'll need to try one on for fit.

These are all just suggestions, depending on your price range you can find similar versions, just try to match the illusrtation as closely as possible. If you're in a store, bring along the picture, it'll be easier to find what you need if you can show people. Best of luck in your searching and if you have any questions, feel free to ask.
