Thank you for the quick reply gents. It's not my wedding so I think this thread is okay.
How formal is the wedding ? There are lots of good deals to be found on eBay, only problem i can see is returns being more of a hassle. Here is a nice suit for a spring/summer wedding at a really good price.
I think the wedding is suit and tie for sure but I don't think not too many will show up in a tux. Have you dealt with this Ebay seller before? He has mostly 3 button suits. Any 2 button suits?
