One of the number one things brides want to do is find THE dress! While dress shopping is one of my favorite parts of the planning process, it can also be very stressful. Most brides think they know what they want...until they go to try on gowns. A bride who thought she wanted simple, can often change her mind to sparkly and intricate. Whereas, a bride who thought she'd go for the glamour, ends up with a simple, yet elegant gown. Whatever you think your style is, don't decide on it 100% until you try on dresses.
That being said, once you know what style suits you best, you can start looking into some online resources. Not all brides are into the idea of "previously loved" gowns. But if you are willing to at least take a look, check out Once Wed. They offer a classified service for wedding gowns. Some have been previously worn, but others have not. Some brides order two (or three!) dresses because they can't decide. Then when it comes down to it, only wear one. So, some dresses on there are new with tags, some just never been worn. The least expensive wedding dress on there that I have seen is $60!
