The actress rarely gets it wrong on the red carpet, opting for bold yet flattering dresses by designers like Versace, Elie Saab and Dolce & Gabbana. In honor of Jones’ 34th birthday, Us Weekly has compiled her 15 most memorable looks over the years.

Though she often wears fashion-forward, risque ensembles, Jones still appreciates her ’60s Mad Men wardrobe.

“The long-line bra with the pointy tips and the girdle and then the stocking on the garter belt, I really like the shape it gives me,” she told Allure in 2011. “It’s kind of sad when you take the girdle off at the end of the day.”

Back in June the celebrity stylist flipped out when Jennifer Lopez, 42, was photographed in Paris wearing a white tuxedo dress that Zoe designed for her debut collection.

“Seeing Jennifer Lopez in the tuxedo dress was one of the most surreal and exciting moments of my entire career,” the reality TV star gushed. “I said, ‘When I see a total stranger wearing my clothes, that’s going to be amazing.’ When I see anybody wearing my clothes — that’s going to be amazing, but that was on a whole other level of insanity.”

And on Wednesday night, Hollywood’s latest “it” girl Julianne Hough, 23, rocked the same style in black to the New York City premiere of Footloose.

Rachel Zoe, 38, is six months pregnant with her first child, she’s in the process of launching her own eponymous line and she needs to hire a new assistant, like, now. Here, the top five moments that everyone is talking about from the premiere episode:

1. It’s a boy! The famously skinny stylist is rocking a (teeny tiny) baby bump, and seems absolutely thrilled with the impending arrival of her “peanut.” However, she admits that she cried for days when she found out that she was having a boy instead of a mini-me she could deck out in designer duds.

2. She’s mad at Brad. Though Zoe and her former employee, Brad Goreski, said their split was amicable when they announced the news last September, it seems like there are hard feelings between the two. “It’s not the first time I’ve been used,” she says after revealing that within a week of parting, Brad went out on his own as a stylist and pursued her clients. “I would say it’s going to be the last time, though.”

3. Team Zoe is expanding. Rachel is instantly smitten with junior stylist prospect Jeremiah Brent (he’s adorable and makes her laugh) and decides to hire him at the end of the show. We also met Mandana Dayani, the new Director of Brand Development for Rachel Zoe Inc., who Rachel brilliantly refers to as an “execubitch.”

4. All you need is love. Rachel and her husband Rodger Berman channel Yoko and John Lennon in a glam photo shoot for ELLE magazine, where the couple poses in Givenchy (her) and Tom Ford (him) while lounging in bed. But it’s not too literal, as Rachel says, “”We aren’t making me Asian.”

5. Witchy woman. Rodger finds a home that just might be too big for their growing family. However, Rachel loves the place (despite having only seen photos of the manse) and says she has a “witchy vibe” that it’s the perfect house for them.
