Do you have a Salvation Army Store near you? Or a consignment shop? I frequent our SA Store and there are currently a couple wedding gowns of questionable class (so many beads and bling they must weigh a ton

) and some pretty hideous gowns. Extremely cheap!!! If you do have any, keep an eye out for half-off day. Good luck - that's a super idea. You must post pics.
OOP! Just reread your OP. Missed the last sentence, lol. I'll be happy to check back at ours. I think the one dress was about $45 and a size 10 or 12. But, my memory only lasts about 20 minutes, so I'll have to go back and check again
