We've long been obsessed with Tinsley Mortimer's girly, chic vacation style. Let's review, shall we?

The Real Housewives of New York City fashionista wears a high-waisted bikini — and oodles of bling — for a poolside relaxation session. When she's seeing the city sights abroad, she's paired a short, floaty dress with glamorous sneakers. And when she heads to the desert, as we now know, Tinsley has a flirty dress that channels a southwestern color palette. 

In a March 31 Instagram post, Tinsley looked ready for mountainside cocktails in a short patterned dress by one of her go-to designers: Alice + Olivia. (In the clip above, watch Sonja Morgan tell Tinsley that she "has the body for Alice + Olivia.")

With a V neckline and a lantern skirt, the structured dress is embroidered in desert shades of yellow, orange, and red. The Real Housewife paired the look with gold shoes, a pile of gold bracelets, and a fresh blow-out. 

"Does this dress say New Mexico or what?!" Tinsley wrote in her caption. 

If you're headed to the desert yourself, or just need a great cocktail dress for the upcoming patio season, scroll down to see where to shop the style. And in the meantime, be sure to catch new episodes of RHONY every Wednesday at 9/8 c.
