Heading for a wedding

Okay, so I get married in 3 months and I was expecting planning a wedding to be an exciting job, it really isn't. The amount of things to do is mind boggling and we're only having 50 guests! Early on I decided on the style of dress I'm having and found someone locally to make it for me. I also decided on my bridesmaids dresses too and they set the tone for the day:

They're going to have tiered cotton underskirts to really make the most of the circle skirt. But my main niggle now is what colour suits the men could have? Any ideas welcome :) x
