Upon first glance of Elle Fanning's recent airport style, I have to admit I was a tad thrown off by her 3x1 Denim cropped jeans with frayed fringed hems ($295). It could just be the fact that her socks are peeking out of her platform shoes - a styling detail I'd personally avoid - because otherwise, the boho fringe is a fun departure from the skinny jeans and ankle boot combos we're so used to seeing. Add a cozy turtleneck sweater and wool fedora, both in black, and you've got a chic look that's perfect for casual outings. Read on to get our look for less...

Actress Busy Philipps showed off some new blue-hued locks recently against a neutral backdrop, donning a Forever 21 olive trench, dark gray mini dress and black ankle boots for a day of pampering. Her sleek blonde tresses with just a hint of blue ombre on the tips look fun and modern (and almost makes me want to color my own hair!) With temporary hair dyes on the market today, it's an easy DIY look to achieve with little commitment or cash. Have you experimented with rainbow hued hair? Read on to snag Busy's exact Forever 21 coat for under $50 (a great fall layering piece), plus more fashion lookalikes to complete her look...

Penelope Cruz, the new face of Carpisa, arrived at the store in Milan to launch her new capsule collection co-created with sister Monica wearing a striped sweater and skinny jeans. At first I thought her outfit was awfully casual for a launch party but then realized she's wearing this Saint Laurent sweater, which costs $1,150 at barneys.com. I think that qualifies as fancy. What I love about this look is that we all have a striped sweater and skinny jeans, but it's those over-the-knee boots and her chic hat that take this outfit to the next level.
