Already, Rebecca Minkoff's new denim line has many fans including Stacy Keibler and "Girls" star, Zosia Mamet. 

According to InStyle, her RM Denim & Tees is a new extension of her designs, possessing an "everyday cool."  She recently debuted the stylish line at a rooftop dinner in New York City's Mandrian Soho, bringing out on-screen actresses with off-screen fashionista tendancies.

She showed off a modish collection of "jeans, shorts and slouchy worn-in shirts," which each piece is named after a Manhattan Street. 

And a good portion of each purchase goes to charity. For each piece sold, a portion of proceeds will be donated to the Share our Strength's No Kid Hungry Initiative. 

The designer's first foray into denimland comes after taking the shoe and handbags world by storm. Her new separates are made from "locally sourced power-stretched fabrics" and are available in five denim styles for plenty of styling options, according to FabSugar. 

To check out or buy the pieces retailing for $48 to $128, visit rebeccaminkoff.com or head to her denim pop-up shop at 96 Greene Street in Soho until July 9 if you're in NYC.

In related news, NIVEA announced that Minkoff is partnering with them to spearhead a new lip care design campaign to celebrate "consumers' personal style," according to a press release.

The "Style, Uncapped" campaign allows "consumers to design and purchase their own lip care caps and customize each kiss occasion." Minkoff created a limited-edition design inspired by her Spring 2013 collection. 

"I'm thrilled to be partnering with NIVEA, " Minkoff said. "Like the brand, I appreciate and encourage self-expression. With this first of its kind program, we will give everyone in America the opportunity to make their lip cap their best accessory - and I know all too well about the importance of a great accessory."
