All weddings use tradition, either to build from or avoid.
Southern weddings are much like other events, but steeped in traditional southern ideals. Some of the practices have to do with the heat, such as choosing late afternoon or early evening to have the wedding. Other considerations have to do with courtesy and tradition, such as only the bride wearing white no matter what. Gifts should be offered and there are a few things you can give to prove your southern knowledge.

Don't Bring Gifts to the Wedding
One of the most important facts of a truly southern wedding is the fact guests do not bring gifts to the reception. It is considered in poor form to put a gift table at the reception, so gifts are given to the bride and groom in advance by sending them to their home. It is fine to take your time and send a gift after the celebration. Many people do this as well because they can then put a personal note in the card referencing the wedding. If you are invited to a shower and provide a gift at that time, you are not required to give a gift at the wedding as well.

Silver Spoon Collectibles
Silver spoons have long been a collector's item in the South. You can find them at antique stores or you can purchase them at gift shops. These can be a nice way to commemorate the history of the couple by giving spoons from areas with which they have a history. Another option is to get a real southern silver tea set. This is a throwback to the days of wraparound porches.

Southern Baskets
Southerners are found of their gift baskets. Because gifts are sent in advance or after the wedding, you can send a basket of edibles to the happy couple. This can be a nice touch, giving them some of their favorites before the big day. As it is likely they are busy with family, it can help keep them fed while they are too busy to cook. Places like the Atlanta Gift Basketier will deliver anywhere.

Prayer Gifts
Prayers are usually an integral part of a southern wedding. There are a number of different articles that can offer marital advice. Collector's plates, frames and pillows can be emblazoned with the "Happy Home Prayer," and are a great way to offer your blessings for the newlyweds.

Registries
As with all weddings, you're most likely to please the couple by shopping off their registry. Whether from the South or not, couple's enjoy opening gifts they have expressed an interest in by registering. When you work from such a list you can be sure you are getting something the couple wants or needs for their new life together.
