Bachelor Party, free online invitations
The bachelor party planning traditionally falls to the best man, but it can also be handled by the groom's brother or another good friend. All the guys in the wedding party get an invite, but it can also include other close friends and family; just ask the groom to put together a guest list. Technically, etiquette even allows inviting guys who aren't invited to the wedding, but since herding a big bunch of bachelors can lead to headaches well before the hangover, only go there if the groom specifically requests it. Extra points if you invite the bachelor's dad and even future father-in-law to the dinner portion of the evening — just be sure to see them off after dessert, before the real late-night debauchery begins. Whatever you do, don't plan the bachelor party the night before the wedding. That's usually reserved for the rehearsal dinner, and besides, hangovers and getting hitched don't mix. If you must (that is, if all the groom's nearest and dearest live far away and can't travel until the wedding), you could consider doing it the night before the rehearsal dinner, but it's generally much better to hold it at least a week and up to three months prior to the big day.
