Keyshia's lace-up caged 'DIVA' booties are almost identical to the Alice+Olivia pair...minus about $400. They come in black leather and a metallic pewter color. You can buy them here.
I'm not sure which came first, but if you like the Alice+Olivia pair better, some sizes are still available here.
Very interesting!! Now I'm wondering how much input Keyshia actually had in this collaboration. Regardless, these were the shoes I was eying from her line (and I like the Steve Madden price point much better!).
