Who pays for groomsmen suits
The first thing you need to know is that your suit should be a compliment to everyone else's suit. No, not the same as everyone else's suit - it needs to make sense with what they will be wearing as well as for the overall wedding stylings. So if the bridesmaids are all wearing black cocktail dresses and there's a dark evening wedding in winter, it's probably not the best time to break out the white linen suit.
Now that we've gotten that out of the way, let's go over some finer points about groomsmen suits! The first thing you should consider is whether or not you want them to wear matching suits. We do not recommend this for several reasons, but one of the biggest ones is that each suit won't necessarily fit your groomsmen as well as it would if they were wearing their own suit. Besides, you can always buy them dress shirts to match or coordinate with any ties or pocket squares that you might be looking into.
Another thing to consider is where your groomsmen will be before the wedding. If they'll be at a resort or somewhere with no dressing rooms, it's probably worthwhile to find them something simple and affordable that doesn't take much work on their part. Buy them a suit in a color that compliments what your other groomsmen will be wearing and they should be good to go!
A third thing to consider is their height. It should go without saying that shorter groomsmen might want a suit that's a little more forgiving on the legs, while tall groomsmen might need something with an extra inch or two in the length of the pants.
