The loose, unstructured shape of the slip dress is evocative of flappers from the roaring '20s, making it ideal for a vintage wedding look. Wear a retro slip wedding gown with blush-colored silk or sparkly tassels to channel your nostalgic side. For a more modern take on the dress, pair a simple white slip with silver jewelry and high heels. The informal nature of a retro wedding means that you can choose whatever style dresses you like, as long as they are easy to move around in. A-line, ballgown, and tea length dresses are all elegant choices, while longer dresses are appropriate for women who may not be able to fit into short clothes anymore. Avoid wearing tight dresses to a retro wedding; it's better to look good than feel uncomfortable. Retro weddings often have an old school theme, so choose decor that fits in with this idea; for example, if you are having a beach wedding then perhaps keep the ceremony and reception inside. If you want to add some flavor to your wedding party dresses, consider using flower petals or lace instead of traditional flowers. Finally, remember to have fun with this project! Create a look that reflects your personality and has something timeless about it. You don't need to follow any rules when choosing clothes for a retro wedding; just make sure you are comfortable wearing them and that they fit well.
