My fiance has chosen his best man and two groomsmen for our wedding. However, now he tells me that two of them won't be able to afford a suit rental and just want to go with black dress pants they already own and maybe a white dress shirt.I'm having an issue with this, First of all, there are different styles and shades of black. I wanted them to all match! Its just not going to look right. No jackets or vests? Am I over- reacting? Any ideas on how to do this?
