Like Ginger said, once they shipped it out, it usually comes pretty fast (within a week).
I think someone order a tulle/lace dress from them a few page ago, it turned out very nice. You can also goto their website, they got a gallery with their previously made dresses, so you can have some ideas. Ginger's new dress is a lace dress as well.
It is a great idea to donate some dresses to girls who can't afford a prom dress (so much fuzz about going to a prom nowadays!) I will drop my MOH dress that I weared last year to the donation box too! I don't think I will wear a purple taffeta long dress in the near future anyway.
But your wedding is in November, so you may still order more dresses!!! hahaha
LOL! a 6th dress?! I think my FI will start to complaint! He will just have a linen shirt plus linen pants!!
