Casual Groomsmen Attire

A casual wedding style call for a casual groomsmen attire, like a suit. Lighter colors like tan, grey and light grey are all neutral, casual suit shades that will work well with almost any wedding color, the darker colors call for a more formal wedding. 

Casual weddings are in general a little more colorful, but for the wedding party a neutral colored suit is definitely recommended, because it can be very overwhelming if too many people are wearing the same bold color. 

Instead of putting your groomsmen into a full on bold colored suit, work those color into the outfits through the accessories. As far as the type of neckwear, neckties are more casual, but the right bow tie can make a casual suit a lot more interesting.
