In a wedding with a casual dress code, you have more freedom in what colors you can wear, and so don’t be afraid to belittle things with some pastel colors. If you are a man, it is possible to combine a vest that matches your jacket or trousers for additional elements for the Casual Chic Summer Wedding Outfit. Contemporary shirts often don’t have collars that can be removed in any case. Bow tie can be used instead of a tie.
