JonetteA, hope you are familiar with the Baton Rouge area, but if not I'll email the addresses of these shops.
I went to D'Lei's which is on Jefferson Highway near Parkview Baptist School. They had quite a number of dresses such as most of their Maggie Sottero, Demetrios and Moonlight 1/2 off. Only drawback is that the 1/2 price dresses are the ones right off the floor (this is the same with all the bridal shops). You have to deal with the sizes they have available. I'm a little large, so I didn't have as much choices as others. However, the dress I purchased today was one size smaller than I would wear. I'm not worried about losing that weight though. Plus since I have the dress at home with me, it is super incentive to lose it!
D'Lei's also carries the Alfred Angelo dresses which are somewhat less expensive than others lines. Many are very attractive and I'm eyeing one for my Vow Renewal. Got to lose another 10 pounds though to try it on and make sure.
Gabrielle's Bridal Shop in the Drusilla Shopping center next to Drusilla seafood has a backroom filled with very, very inexpensive dresses (as of last Saturday). Most were under $350. They are getting rid of their Maggie Sottero line because of problems with the company so they have a lot of those. They also carry Justin Alexander, Sincerity, and LaSposa, as well as several other lines. I'm eyeing one of those too.
Bridal Boutique (across from Cortana Mall on Florida) has lots of sale dresses and probably carries the most lines. Just about all of them. They had a good selection, but I just couldn't make a decision.
Pearl's Place in Metairie also has tons of dresses including lots of sale dresses and is a good resource too if you can make it there.
It is very difficult to pick THE ONE dress for the ceremony. I loved a number of sales dresses, but just am not sure yet. However, the dress for my anniversary party was a great deal and I'm very pleased with it.
Good Luck and let me know if you need specific directions or more info.
