Pay for their travel (if from out of town). Lodging expenses are ordinarily borne by the groom but it can vary.
If the groomsmen will be renting their tuxedos, it is preferable they do it from the same shop, so that the styles or shades don’t differ drastically.
If you’re having an outdoor reception/ceremony and it’s likely to be warm, the male attendants should consider wearing vests with full backs so that they can safely knock off their coats.
