Mia Thornton never shies away from posting a sexy Instagram picture, whether she's wearing dreamy white lingerie or rocking a bold beauty look. Most recently, The Real Housewives of Potomac cast member shared a slew of snaps from her 37th birthday celebration in the Bahamas including a sexy "Midnight Snack Run" and a sneak peek of a romantic dinner. But, Mia's latest picture was the most sizzling yet.

On November 29, Mia took to Instagram to share her red-hot vacation ensemble. Dressed in a scarlet bikini, Mia walked hand-in-hand with her husband Gordon Thornton along the water. Mia's two-piece bathing suit effortlessly accentuated her curves while also complementing her sunkissed skin and dark hair. The bikini featured a cute tie detail in the middle, which looked similar to the bust of her dinner outfit from the night before.

Mia captioned the photo, "Hey Zaddy," showing some love for her husband.

Mia also put her sexy fashion sense on display at the RHOP Season 6 reunion. "I just decided to just be fun and bring on a little glam," she said of her debut reunion look, a skin-baring Brides By Nona Couture number, in the Bravo Insider video above. "I love it."
