Dinner jackets are typically worn from May to September, but they are also worn all year round in warmer climates and on cruise ships.  We offer two types of dinner jackets that are very similar in style.  However, the polyester dinner jacket is pure white, and the wool jacket has an off white (winter white) color.  All wool dinner jackets are only made in off white or ivory.   Enjoy shopping, and feel confident in knowing that you are getting a great deal on a brand new dinner jacket.  Please remember that there is free shipping on all orders over $100.
