A best bet is the Michael by Michael Kors Men's Solid Suit in Navy for $199.99 before coupon,
$189.99 $169.99 after. With free shipping, that's $165 less than the lowest total price we could find for any Michael by Michael Kors navy suit. It's available in regular, short, and long lengths in sizes 36 to 50, although not in all size/length combinations.
Update: For a greater discount on orders of $100 or more, coupon code "TXTCLB" cuts an extra 15% off. It reduces the price of the best bet above.
