Groomsmen are the close friends or family members chosen by the groom to support him on his wedding day. They play a vital role in helping the groom prepare for the ceremony, often assisting with tasks like planning the bachelor party and ensuring everything runs smoothly. Groomsmen typically wear matching attire, such as suits or tuxedos, to complement the groom's outfit. During the wedding, groomsmen stand by the groom at the altar and participate in various traditions, such as giving speeches at the reception. Their presence adds to the celebration, making the day more memorable for the couple and their guests.
