This week, the trend-setters ditched the bland basics and opted for candy colored pants and polka-dotted patterns. Spring is the time to clean up your act and shed those excess layers -- start fresh with bright hues and funky prints, you won't regret it!

Rachel Bilson paired her J Brand capri pants in a cotton candy pink hue with a Vanessa Bruno embroidered silk blouse and towering Charlotte Olympia platform pumps. We loved her ensemble so much that we took it upon ourselves to hunt down the actress' look, for less.

As the recently hired artistic director at Theory, Olivier Theyskens has taken the fashion world by storm with his luxurious basics. While attending the premiere of "L'amour Fou" in NYC the designer kept it neutral on top with a gray blazer and long-sleeved cream shirt. Theyskens opted for a bold statement below the belt with cobalt blue trousers and matching shoes.

Hayden Panettiere arrived at Los Angeles International Airport wearing a revealing tank top and J Brand 811 skinny jeans. She tucked her bright, purple pants into a pair of motorcycle boots and chose a basic, black leather handbag.

Singer Rihanna wore a dotted Miu Miu blouse with a pair of J Brand denim cuffed shorts while leaving Philippe Chow restaurant. We loved smart accessories like Prada ankle-strap pumps, blue headband and charm necklace.

Kate Middleton
stepped out the day before her royal wedding in a sophisticated wrap dress. We love that she mixed the patterned frock with a cream colored ruffle cardigan and wedge heels. Kohl-rimmed eyes and carefree tresses were perfect -- oh, and that bride-to-be glow!

For Easter Sunday brunch, Beyoncé donned a sophisticated look straight from the Marc Jacobs Fall 2011 runway. The dual-colored dress features a prominent polka-dot print which the singer paired with Christian Louboutin navy heels and a black crocodile Balmain bag.
