The actress' tiny waist was highlighted by the silver beaded belt that separated the feathered fringed bottom half of the dress on the cover.

Her blonde hair was voluminous and wavy, cascading down her shoulders. 

The singer held onto a leather jacket, which had silver zipper detailing, draping it on one shoulder. Her other hand was perched atop her full skirt, decked out in several silver bracelets and rings.

The stylist for the shoot, Karen Levitt, shared an additional photo from the shoot, with Hilary rocking a Sonia Rykiel star patterned top, Fendi sunglasses, and an Eddie Borgo choker.

For the fall cover, the starlet wore pink glossy lips, subtle smokey eyes, rosy cheeks and defined brows.

For the past few weeks, the former Disney starlet has been spotted all over New York City filming new season of her TV Land show.

On Thursday, the mom of one was caught filming the show, dressed in a black mini skirt, a bird patterned collared shirt and a grey long vest. 

Her toned legs were on full display in the short skirt, which she paired with light grey booties.

Layer it up with Hilary Duff's wool long vest

Hilary Duff looked fresh like a daisy as she stepped off the set of the HBO series Younger in New York this week. Adjusting to the colder temperature, she had gone for a bird print blouse with a black skort and layered it with a long vest in grey melange from Rag & Bones.

A sleeveless wool coat is just ideal on a crisp autumn day. Team it with either a blouse, T-shirt or a cashmere sweater to make your off-duty style light while staying warm. Hils has boldly chosen a bare-legged approach (we're guessing the New York weather still allows it!) but style it with ripped jeans or black skinny trousers for those chilly mornings. Complete your loose-fit silhouette with a pair of over the knee boots to achieve that casual chic look. We're thinking grey suede! Top things off with a fedora hat, and your look couldn’t be more on trend.

Get ready to layer up with Hilary’s version (right) or take a moment to investigate our vest options below!
