Who doesn't love a good bonding sesh for Kyle Richards and Kim Richards?

Last night, The Real Housewives of Beverly Hills stars left the other Housewives — and all men — behind for a little sisterhood of the traveling cocktail dresses.

Kim shared the red carpet group photo below, writing, "Too fun #2014cableshow #comcast #bravotv #rhobh." She also shared this closeup with Kyle sporting her own glorious hat (do we call them "fascinators"?) in keeping with what was apparently a speakeasy theme. "What a GREAT NIGHT witth My Beautiful Sister❤,” Kim gushed. Aww!

Kyle previewed her hot pink ensemble in this Facebook photo set in her home, writing, "I love the length & color of this #herveleger @kylebyalenetoo about to hit the town with @kimrichards11."

She’s gorgeous! You have to check out the full look.

It’s always good to see Kim and Kyle spending time together — the RHOBH ladies are very different in how they approach things, but they’re both beauties and we can’t wait to see what’s next for them.

Kyle recently hinted to a big shift coming on RHOBH Season 5. "It's gonna be very interesting," Kyle told Andy Cohen on Watch What Happens Live. "Things have changed a lot, and — even though there's been a big divide, and the relationships have changed a lot — I think everybody's grown a lot and learned a lot."

Interesting indeed. Whatever happens, hopefully Kim and Kyle will still have each other’s backs. Team Richards for life!
