Despite her growing baby bump, Jessica Simpson has been looking as stylish and sexy as ever. The mom-to-be, 31, rocked a skin-tight red Donna Karan dress at the Footwear News Achievement Awards in New York City last month and wore her super long blonde hair curled and in a half-up style.

"I wanted to create a look that was soft and fresh to complement the glow in her face, yet elegant enough to accent the great dress she wore," celebrity stylist and Moroccanoil Global Brand Ambassador Robert Vetica tells Us Weekly.

After applying Moroccanoil Treatment and blow-drying the star's hair, Vetica used a 3/4 inch curling iron to create a bouncy base.

"I directed the curls away from her face, then sprayed her hair with Moroccanoil Luminous Hairspray for a manageable hold that let the hair move and gave it a brilliant shine."

He then brushed through her hair and teased a large section at the top before pulling it back to the crown. Next, he twisted the teased section and secured it with Untamed Petals' sparkly "Leaf Clip."

Finally, he pulled some of the hair on her left side toward the front and finished with more hairspray as well as a mist of Moroccanoil Glimmer Shine Spray for added sheen.
