Who can attend bachelor party's?

Bachelor parties are typically attended by the groom's close friends and family, including the best man, groomsmen, and sometimes other male relatives. The guest list can vary based on the groom's preferences, but it's generally a celebration meant for those closest to him. In some modern contexts, the event may also include women, especially if the groom has a more inclusive approach. Ultimately, the attendees are determined by the groom and the best man.
