Fab or flop: Elizabeth Hurley's sexy blue dress, Selena Gomez's nude leather pants and more

As stars stepped out to promote new projects, hit the hottest shopping streets or attend glamorous events this week, they strived to achieve the best fall style. We saw many boyfriend or girlfriend jeans, long robe coats and over-the-knee boots.

We especially loved Karlie Kloss' timeless look as she hit the streets of NYC. She sported a striped turtleneck sweater, tan trench coat, blue jeans and over-the-knee suede boots (get the look here). We love the purse she paired with the look to make it exceptionally chic! She looked casual, crisp and classy. We also loved Elizabeth Hurley's evening look in NYC. She wore a figure-hugging blue dress (similar style here) that accentuated her curves in the best way. She looked sexy yet sophisticated. We loved the glamorous oversized shades and she accessorized perfectly with simple yet elegant pointed toe heels and a nude clutch.

As for flops, the biggest fashion issue stars struggled with this week was accessorizing. Many sported perfectly acceptable staples but paired them with shapeless sweaters, bulky bags or overly simple shoes. Jennifer Garner, for example, rocked a bohemian-style skirt that could have looked great with the proper pairings. Unfortunately, the skirt lost its edge when paired with a simple sweater and plain black flats.
