The reality stars look fierce in the new pics, with Ariana taking center stage as she flaunts a lot of skin in her red revenge dress. She's also got a healthy amount of bling on her fingers, too.

Raquel Leviss' look is a lot tamer, relatively speaking, as she's rockin' a mint green outfit along with a look of deep concern. Tom Sandoval, at the top of this love triangle, went with a classic suit sans tie.

Bravo showed off everyone else's 'fits, too -- Scheana Shay looks great in a sparkly dress, Tom Schwartz is all smiles in his blue corduroy, Lala Kent stepped out in a leopard-print piece, and Lisa Vanderpump rightfully wore ALL the diamonds with her black dress.

As we reported, Tom and Raquel were spotted having a serious heart-to-heart on reunion day ... unclear what they were chatting about, but you know all the drama surrounding them must've been on their minds.

No word on a specific airdate for the reunion, only that it'll be in late spring -- but we're on the edge of our seats, waiting for it all to unfold.
