Well, a two girl party with you and any of those ladies would be fantastic, but as I follow Allissa on twitter and have had twitter talks with her, she would be my first choice. Would have partied with her for sure on my visit in May, but I missed her by one day.
I want to start by saying that although i have not met Red Diamonds, I find her to be gorgeous. I have not met any of the girls on your wish list there, but based on my findings online, I would say that Fabienne has beauty that makes the Diamonds that are Red shine even brighter, and so in my humble opinion, considering many psychological and physiological factors, I would say that this set up would be the ideal two-girl party. I also going to go out on a limb here and say that Red Diamonds would be such and amazing experience on a more personalized setting as well. I wish all the girls were twins, but sadly only two of them are.
