Yesterday I got three of my four guys (groom included in the 3) to buy/decide their attire. One of my BMs and I scoped out men's stuff a few weeks ago. I picked out some stuff at Men's Wearhouse but needed to get the guys in as well as get my MOH's dress in the store (the colors are based on her dress, which is green). FI wanted to buy a suit since he doesn't own one yet. One of the GM already owned a suit, and it turns out Men's Wearhouse carried the same style! The only difference is the MW suits were a bit shinier (something do with the blend of material), but when they stood together, you couldn't even tell. So they all have matching suits!
Fi will be wearing an ivory shirt + ivory tie. The two GMs will be wearing a black shirt + green/black striped tie. The best man was unable to come, but he also already owns a suit. All I have left to do is find his shirt (Men's Wearhouse didn't have a green that matched the MOH's dress) and have a look at the suit he has (which I'm pretty sure it's ok--I've seen it once before). He'll also be wearing the striped tie.
I still feel like I got a lot taken care of there, though. Phew!
