On the red carpet: Margot Robbie, Saoirse Ronan, Diane Kruger and Cheryl

The celebrities on the red carpet this week...

1. Margot Robbie

Margot Robbie was lovely in Rodarte at the Mary, Queen of Scots’ premiere.

The brand, one of just 14% in fashion headed by women, is named for the designers’ Mexican mother and currently the subject of a National Museum of Women in the Arts exhibition in Washington DC.

2.Saoirse Ronan

Saoirse Ronan looks wonderful in Caroline Herrera at the same event.

She and Robbie have been taking turns with those regally-high necklines.

Margot had a crystal-throated Chanel last week in New York while Saoirse went with V-necked Gucci.

3. Diane Kruger

Diane Kruger wore Ralph and Russo Couture to the Hollywood premiere of Welcome to Marwen.

This dress isn’t so much lingerie-inspired as the real deal. The lace is beautiful but so exposing I want to pull a trench coat on just looking at this.

4. Cheryl

Cheryl chose an angelic Zuhair Murad top and skirt for the CapitalFM Jingle Bell Ball. We’ve seen looks like this from this designer and even on this same star numerous times but Christmas is all about replays
