Blake Lively and Anna Kendrick film costumes from A Simple Favor on display...

In director Paul Feig's dark comedy thriller, A Simple Favor, Anna Kendrick plays parenting vlogging mom 'Stephanie Smothers' who befriends the super-secretive, sophisticated fashionista 'Emily Nelson' (Blake Lively) when their kids have a playdate and they bond over martinis. When the mysterious Emily goes missing, Stephanie plays amateur sleuth to get to the bottom of her disappearance and discovers more than she bargained for.

This duo of contrasting costumes from the movie were designed by Renée Ehrlich Kalfus and were photographed on display at Downtown L.A.'s FIDM Museum on February 5, 2019, as part of the 27th annual Art of Motion Picture Costume Design exhibition.

In the feature Blake Lively wears several sharp, vintage tailored outfits like this shirt-less, wide-legged tuxedo pantsuit, whilst Anna Kendrick's softer wardrobe reflects her character's desire to win over followers for her mommy vlogging site.

And considering her character has a penchant for sleek menswear, Lively also sports the director's own skull head walking cane as part of this look.
