I know this typically goes under the classifieds section but I really would rather deal with a local DC bride than have to deal with shipping.  This is an excellent way to save a few dollars if you're interested.  Again, it's a David's Bridal slip style 603.  A lined, 2 tiered, size 10.  It sells for $59 online and I'm selling it for $30.  Let me know if you're interested.  You can see it online at:
