Style in black and white! Olivia Wilde, Rose Byrne and Emmy Rossum matching in monochromatic ensembles to celebrate Target's latest collaboration with Marimekko

The label is known for its bright coloured patterns, but these stars decided to shun all colour.

Olivia Wilde, Rose Byrne and Emmy Rossum rocked darker hued looks at the Marimekko For Target Launch Celebration.

The three actress all hit The High Line's red carpet in New York on Thursday evening looking subtly chic.

As the Finnish company's new collaborative collection for Target is more for hitting the beach then the red carpet, the stars were free to wear whatever they liked and seems they all like black.

Olivia created a masculine but still feminine look by layering different pieces.

The Vinyl star stepped out in a pair of straight leg black pants with a sheer collared shirt featuring a long length of fabric at the back and a suit jacket.

New mom Rose also added a tailored suit jacket but wore a very different look for the event.

The Aussie actress looked sartorially sharp in a pair of flowing culottes with a black and white sport blouse with bow - which she wore undone - detail.

For her baby-free evening - no doubt two-month-old Rocco was with his father Bobby Cannavale - the star wore her ombre locks in a soft curls which fell to her shoulders in a lob.

Emmy meanwhile, wore a shirt dress which featured cutout sleeves and skirt.

The star paired the dress with some statement making black and white Sophia Webster heels featuring a butterfly.

The actress were out in force to promote the latest Target collaboration which hits stores April 17.

Marimekko X Target features not only clothes and swimwear for women and girls, but also homewares and outdoor sporting goods including a paddle board.

Based around the idea of eternal summer - as during the summer in Finland the sun stays out till midnight - the collection is ready for warm weather.
