Finding the right wedding bands are very important. You and your groom will be wearing them everyday for the rest of your lives.
Make sure to go shopping together to find bands that compliment each other. And if you're planning on wearing your wedding band on the same finger as your engagement ring, you'll need to make sure that they fit nicely together.
Check with your officiant to make sure that there are no "ring requirements" for your ceremony. For example, if you're having a Jewish ceremony, the Rabbi will tell you that you need unadorned round gold bands. The solid round band represents your unending love for each other. If you do need special rings for your cermeony, you may want to either purchase simple gold bands for your ceremony, or borrow bands from your parents or grandparents.
The bands pictured above are from the Love, Peace and Hope Bridal Jewelry Collection. 10% of every purchase from their new line of engagement, wedding and anniversary rings is donated to Lambda Legal, a national advocacy organization working towards marriage equality.
