Lisa Rinna just tantalized her 2.7 million Instagram followers with her most recent post, a steamy snapshot in which she flaunted her bodacious curves in a plunging dress. The mother of two did a photoshoot for her new lip kit collection for Rinna Beauty — a makeup line that she created.

Lisa rocked a dark blue satin dress for the special occasion. The garment was sleeveless with thin straps that crisscrossed behind her back and clung over her shoulders. It also had a plunging neckline that reached her midsection — showcasing a nice look at her décolletage. Notably, the sides are pretty low-cut that it displayed a glimpse of her sideboob, and it made many viewers happy.

While only the upper part of her dress was shown in the pic, the whole piece could be seen from her other post — a short clip of Lisa walking away from the camera while holding the sides of her dress. The whole outfit reached the floor, and it even featured a train. Lisa wore a pair of high-heeled sandals to complete her look. The reality star also ditched her usual hairstyle for a longer do with a light blond color. Her locks were styled in loose waves, framing her face.
