This week was all about shimmer. And the winners are...

Taylor Swift in a lavender Marchesa gown at the 2010 ACM Awards. The embroidered detailing along the illusionary inset chest and bodice of this gown added a romantic touch.

Jennifer Lopez getting leggy in Georges Chakra at the Us Weekly Hot Hollywood Style Issue Celebration. Gold ghingham detailing gave this dress a truly luxe feel.

Julianne Hough glowing in a white Basil Soda gown at the 2010 ACM Awards. Metallic, shieldlike detailing along the bodice added more dimension to the otherwise simplistic dress.

Halle Berry rocking a nude Gucci number at the 30th Anniversary Silver Rose Gala and Auction. Cutouts along the shoulder and midriff, along with a metallic neckline, were the saucy staples of this sheath.

Carrie Underwood shimmering in a champagne-colored Basil Soda dress at the 2010 ACM Awards. Precise pleating all over this dress, culminating at the one shoulder, proved perfection.
