Dame Helen Mirren Looks Dame Good On Our Best-Dressed List

There must have been something in the water this week. Hollywood's most stylish stars stepped out in monochromatic looks that were strikingly similar.

Helen Mirren and Susan Sarandon both looked ravishing in long, navy gowns with panel details, while Heidi Klum and Freida Pinto proved that sometimes wearing head-to-toe black is the best way to secure a spot on the best-dressed list.

Check out the most stylish outfits from the past couple of days and let us know if you agree with our picks.

Dame Helen Mirren looks dame good in this long-sleeve, shimmery navy dress. Not only does the rich color pop against her fair skin, but the panelling on the sides help to define her narrow shape and makes for one über flattering look.

Another gorgeous lady in navy. Sarandon is fashion forward yet sophisticated in this high-slit gown with mesh detailing. The V-neck draws your attention to her glowing complexion, while the black panels on the side create a beautiful silhouette.

Though we love to see Solange in prints, this monochromatic outfit is a nice change. It's still bright and bold, but gives off a new vibe. The high slit on the skirt is balanced by her long hemline and shaggy, oversized coat.

Sometimes, black is best. This simple outfit could have been boring, but the halter neckline, color-blocked pumps and dark red lipstick made it one ensemble to remember.

If you have legs that look like this, it's a crime to keep them hidden. This micro-mini dress offers just the right amount of sex appeal. Since it is so short, the model was smart to avoid a super tight fit.

Peplums are so flattering, especially when worn with a tight pencil skirt. Vergara's top cinches in at the waist, defining her most narrow part, while the rest of her outfit showcases her gorgeous curves. She looks both fresh and modern.

When you hear gold metallic turtleneck dress, you don't automatically think best dressed, but that's why we adore this look. It could have easily skewed costume-y, but the styling of the look was so on-point (with the slicked-back hair, red lipstick and stappy shoes), that the actress looks like a fashion icon.
