Jessica Simpson is hot to trot!

The 35-year-old fashion designer showed off her incredible physique in New York City this week when she stepped out in a multi-colored mini-dress for a date night with her husband, Eric Johnson.

She teamed the tight dress, which showcased her long and very sculpted legs, with a set of nude heels and her hair down in curls.

The former songbird's spicy outfit was just one of several hot looks she wore that day as she promoted the 10th anniversary of her Jessica Simpson Collection. Earlier in the evening she stopped by "The Tonight Show Starring Jimmy Fallon," and she donned a more conservative style, opting for a black Elie Saab jumpsuit with an embellished, beaded top and a belt to cinch in her tiny waist. She wore her blonde locks down in tousled curls.

"I'm in shock. Just being here in New York right now and having the billboards in Times Square — it's the most humbling experience of my life. I feel so blessed," Simpson dished to Fallon of her brand's big milestone.

Based on her personal style and her brand's success -- it looks like she's doing something right!
