Style Source: Annabelle Dexter-Jones

Who is Annabelle Dexter-Jones? She is the adorable and super-stylish half-sister of Samantha, Charlotte and Mark Ronson (by way of her mother Ann Dexter-Jones' marriage to Mick Jones, after divorcing first husband, real estate entrepreneur Laurence Ronson). Got that? Phew.

The New Yorker loves to mix feminine clothing with more tomboyish elements - think red lipstick and dresses worn with red lipstick and dresses. She prefers a fresh face and a messy bun, only sometimes wearing a made up face or letting her hair down. According to Teen Vogue, her oft-photographed face will be the star of Hogan's upcoming Fall 09 campaign (she has also walked for her half-sister).

We are sure that will be the first of many things to come for the 21-year old model.

Here's how to make some of her spirited, carefree looks your own.

Look 1:

This is one of my favorite AD-J looks. I love the topknot worn with tough black with bits of bright color, like red lips and clothing details. Unfortunately, this Kate Moss for Topshop black minidress is no longer available, but this slash-detail version has the same spirit. We couldn't find a great facsimile of her rad yellow trimmed leather jacket, but try wearing your favorite black version with a skinny yellow scarf draped around the collar loosely to create the same look. Add a union jack handheld bag and some black cutout peep toes and there you have it!

Look 2:

Just like middle school days, Doc Marten's are a must again. Pair with some similarly on-trend bleached denim short-shorts, a worn-in tee (printed or not, that's up to you) and a great, tough, wear with everything black leather bag.

Clockwise from top left: Alena Bleached Denim Short, $19.80 (available at Forever 21); 1460 Women's Boots, $115 (available at Dr. Martens); Lucky Brand "The Wanderer" Leather Hobo Bag, $199 (available at Dillard's); Garden Skull Tee, $26.50 (available at dELiA's).

Look 3:

One part messy bun, one part sparkly tank mixed with one part electric blue mini for a pop of color, toned down by black tights and more shine added with black patent mary janes. Tip: size up for a slouchier, more modern fit on the tank.

Clockwise from top left: Signature Sequined Cashmere Collection: Tank Sweater, $49 (available at Spiegel); BDG Brights Convertible Knit Skirt, $38 (available at Urban Outfitters); Charnos Hosiery 40 Denier Opaque Tights, $8 (available at Figleaves); GUESS Borda Mary Jane, now $84.50 (available at Zappos); Disney Couture Princesses Wrap Bracelet by Kidada Jones, $112.95 (available at N.V. Fine Jewelry).

Look 4:

We rarely see Miss Jones with her hair down and we think she should try this wavy, mussy look more often (though we love a messy bun!). Just as Annabelle did, you can recycle the same peep toes and clutch from Look 1 (stars: oh, they really are just like us), and swap the leather and mini for a black short romper and cropped gray blazer. Complete with a silver cross and silver chain, et voila.
