Men's Wearhouse offers the Pronto Uomo Men's Formal Vest with Euro Tie in Black and Silver for $9.99. Plus, Perfect Fit Rewards members bag free shipping. (Not a member? It's free to sign up.) That's $50 off and quite cheap for such a vest and tie combo. It comes in regular and tall sizes of S to 3XL
and 42W or 50W, although not in all size/color combinations.
