I also have a second floor length red Bill Levkoff bridesmaid dress in a size 10. It is currently discontinued - Style 315. I wore it as a BM in another wedding, and it has also been dry cleaned and is in excellent condition.
If you are interested in having a "similar but different" look to your BM dresses, these two dresses would go well together!
Here is the 315:
I will post photos of the actual gown in my possession soon.
