Make a statement in a skirt like Zendaya's

Cast members of The Greatest Snowman turned on the lights of the Empire State Building, so of course Zendaya was in attendance.

The actress opted for a modest ensemble which included this statement skirt by Martin Grant. Part of the spring 2018 ready-to-wear collection, this vibrant number features a full silhouette, wrap fastening and oversized pockets to create a memorable piece.

Zendaya pulled it off beautifully with a longline coat, crisp white shirt and over-the-knee boots – also ideal for the snowfall!

The real opera singer Jenny Lind was played by Rebecca Ferguson - with singing done by erstwhile The Voice contestant Loren Allred.

She looked chic in a navy blazer over a finely pleated blue mini-dress, giving her outfit a leggy look with a pair of black thigh-high boots. 

Keala Settle plays Lettie Lutz - a woman with a beard - and on Saturday modeled a black and white print dress cinched about the waistline with a black belt.
