Where can we buy my MOM's DRESS???

At first my mom was going to wear the traditional Korean dress throughout my whole wedding but now we decided that she should change into a dress for the reception. Yesterday we ventured out to Roosevelt Field Mall thinking we were going to find something but ZiPPo~! Couldn't find anything! We went to RK Bridal back in January when i got the call that my dress is in and that day my mom tried on some dresses and was told that it would take about 3-4 months to come in if we ordered it.
It is now middle of April and my wedding is beginning of July meaning i only have about 2 months! Is there anywhere that i will be able to buy a really nice MOB dress 'off the rack'?? FYI: I live in Queens!
Thanks girls~!

My mom and I went to so many stores on Long Island, i can't even begin to tell you. She was not crazy about anything at your typical bridal salons so we ventured out to some other stores. Here are a few names and where they are located that were a big hit for us.

Omnibus - Babylon
Isles Fashion - East Norwich
Filly's - Albertson's
She also had found something at Macy's Bridal Salon in Smithtown (also one in Manhasset) but then she thought it wasn't dressy enough for mother of the bride.

HTH.

Good luck with your search.

ETA: I believe you can buy their samples off the racks at each of these stores.

My Daughter's Wedding in Great Neck does have a great selection. My mom actually found her dress there for my brother's wedding last summer, but we actually found the same dress at another store for $300 less!!
