Who: Scarlett Johansson and Cobie Smulders
What: ScarJo rocked as many Spring trends as she possibly could in an embroidered dress by Prada. Floral print? Tick. Peplum? Tick. Lace detailing? Tick. As for her hair and makeup, Heidi-inspired hair isn't exactly on trend, but we like the style paired with her glossy red lip colour, (which also happened to match perfectly with co-star Cobie's dress). Smulders literally smouldered again, this time in a floor-sweeper by Alexandra Vidal paired with a chic updo and the latest red carpet staple - the humble hair band.
Where: The Avengers premiere, Westfield, London, 19 April
Verdict: Scarlett's Prada number is definitely an improvement on the plunging LBD from the Moscow premiere earlier this week and she gets extra fashion points for the best colour co-ordination we've ever seen on the red carpet.
