Ever since our editor Anna suggested Halloween make-up up ideas for Lady Gaga, we thought about how fun it would be to dress up as the over-the-top star. This costume will be fairly simple considering most of us have a great foundation : knee high boots and fishnets/stockings.

The next pieces to complete the now signature Gaga look will be a black leotard and a spool of gold or metallic ribbon to wrap around you. Top off the look with a blonde wig, flat top sunglasses, and black matte nails.Get ready to turn heads everywhere with your poker face!

Actress Katie Cassidy isn't new to TV, but she is new to our fashion radar. The 22-year-old star of the new Melrose Place shines on and off the show with a sleek sultry style. Similiar to her character, Ella, Cassidy favors micro minis and draped pieces that hug her in all the right places. With her windswept tresses and her killer heels, she proves that it is possible to look amazing from head to toe.

The stars shined on the red carpet at the premiere of Michael Jackson's This Is It in curve hugging and glittery gowns. Jennifer Lopez kept it short and sweet in a little black dress and knee high boots, while Katy Perry pulled out all the stops in a long gown with sequins and embellishments. We must say that in a sea of black dresses one of our favorite looks was Paula Abdul's sapphire sweetheart gown worn with pink heels.

Rihanna shows off a multistrand group of knotty neckalces at the Spring 2010 Chanel show in Paris. We know the baubles she has on probably cost a pretty penny, but we've found a way to re-create the look with this fabulous find at Forever 21. Try one for a daytime look and then throw another one on and you're ready for night.

Whitney Port has a way of looking great without doing much when it comes to her hair and makeup. On and off camera she consisentently accentuates her natural feautres without looking overdone.

Left, at Jet nightclub in Vegas where she was hosting an event, she reminds us of '60s French film star and sex kitten Brigitte Bardot with her perfectly parted and teased hair. She further complements the look with long thick lashes and strong eyeliner. We love this look because its subtle but sexy.

Model Gisele Bundchen rocked her baby bump (literally) on a weekend lunch date in New York's West Village in a screen print rock t-shirt, leather motorcycle jacket and black skinnies. We love that she found a way to stay stylish while expecting by wearing some of our favorite fall pieces.

Leopard print has been popping up all over Hollywood. Lately we've seen it show up on the red carpet. Kim Kardashian and Paris Hilton show off their curves in technicolor leopard print dresses, while Padma Lakshmi chooses to go the more demure route with a solid dress and leopard print stilettos. The look is fabulously fun!

We love a great handbag in a pretty color. Lately we've been obsessed with red ones. First we marveled at Sienna Miller's Prada tote, and now we love Rachel Bilson's Blythe Satchel by Jimmy Choo. Not only is the color as delicious as a crip fall apple, but we also love the buckle detailing along the sides. Even in jeans and a t-shirt Rachel's satchel keeps her look polished.

We love spicing up up classic pieces with a wild card, which is why we love this look by Blake Lively. She takes a basic Smythe boyfriend blazer and kicks it up a notch with leather leggings and sky high Giuseppe Zanotti heels. Steal her style for less with our picks.

Christina Aguilera has really stepped up her style game since giving birth to little Max in the winter of 2008. She stays stylish on the red carpet in sleek separates like a pencil skirt, blazer, and skinny jeans. Who said motherhood made you look dowdy?
