Feathered Wedding Dress

Hopefully someone can help me because I don't seem to be having much luck. I am a size 16 street size looking for a feathered wedding dress. I see that a lot of places have a size 10 sample and its obviously not going to help me much. Is there anyone that has wither a larger sample or dresses that are cut larger? (i have no problems with clamps and not zipping but i want to physically be able to get an idea) I have my heart set on feathers. Thanks in advance!
