There is also a third dress that is similar to these two, but it has a weird keyhole opening in the back that I think will look awkward.

I am tempted by these dresses because they are the color I am looking for, and they are only $60. I would be afraid that they may not fit right, and this could involve ordering a number of dresses that may have to be returned. It appears that Overstock will pay for the return shipping by giving you a label to affix to a box to send back, but I'm not sure about the policy. Also, I don't know if they consider "trying on a dress" to be "using" it, therefore, making it unreturnable.
Also, they are tea length dresses. They may be a bit long on some of the bridesmaids. But maybe not.
Would it be worthwhile to order some of these dresses to try on? Or would this be too much of a hassle? If enough people like these dresses, I may order the sizes necessary in a bulk order and we can all try them on. The last concern I had was that the amethyst color is not available online. I don't know if I can call and place a special order, or if I just have to wait for it to come in.
So, give a shout out if you like these dresses enough to pursue them. Or, these could become an alternate if we cannot find any dresses when we go shopping (eventually).
