What color are the suits you have again??
As others said: 1) you want them to look at YOU and not the suit and 2) they won't be able to see your eye color anyway.
I *personally* don't care for velvett - just don't care for how it looks on.....and with your coloring - I really like the green color.....not sure how red would look - but with your darker hair - it might look really good on you.....someone like me (very light blonde) - the blue/black suits look better since I'm so fair.....
