Not to be rude, but what size are you? And not to sound like a salesperson, but I have just posted a lace mermaid dress in the trading post section viewtopic.php?f=91&t=136514
, it's a bit like what you've just described, so I thought I would let you know. The pictures don't to it justice, it is quite a beautiful dress - but not what I ordered and connected to bad feelings for me, so I can't bring myself to wear it. It's worth over $1600, but I am selling for $600. It is quite small, but it is currently zip up, I'm sure a dressmaker would be able to make it lace up to make it bigger. It has beauiful lace & bead embelishments.
I purchased my other dress from bridalgown.net it's great for designer dresses much cheaper than what you would buy them for through a bridal shop.
