We like one of these looks more than the other — but can you guess which way we're leaning???
We're loving Lizzy's sexual side-boob action in an intricately designed ankle-length gown, featuring a leathery waist detail that continued as a strip down the ensemble.
Claire, however, made a mess of her mish-mosh patterned dress, which is totally the wrong cut for this beautiful starlet.
We did like her from the neck up — so that counts as something, right?!
Miz Caplan's hair and makeup was obvious perfection, as well, highlighting the Masters Of Sex star's stunning features!
We can't wait to see what these femmes wear on the red carpet this evening!
