I will be in a wedding when I'm 17 weeks pregnant with #2. We ordered the dresses a few months ago, and I ordered one size bigger than I needed. Since it is #2 I'm now a little worried that my bump will be a lot bigger than it was last time around.

Ordering extra fabric is super expensive (plush rush shipping since BM dress makers are SO SLOW). But I have found a few dresses the same color / material / designer on Ebay for super cheap. Do you think it would work to just buy an extra dress in a random size, and use that as fabric? Or is that crazy? I have no idea how alterations work / if that would even be helpful.

Thanks!
