"Traditionally, the biggest expense that the groom's parents pay for is the rehearsal dinner. Since the rehearsal dinner is paid for by the groom's parents, it is also their responsibility to plan and host the dinner. With the bride's family being so wrapped up with the wedding plans, this can be a huge help. The groom's parents will also typically help with the costs for the groom and his
. attendants like the tuxedos and boutonnieres.Sometimes the groom's parents can feel left out and want to help with more of the wedding planning. A suggestion would be to include them in the planning - have the bride's parents and the groom's parents meet to discuss what they can help with. This can also score you winning points with your future in-laws! More helpful tips on wedding traditions can be found here: http://weddings.about.com/od/theweddingparty/a/momofthegroom.htm"
