Maisie Williams puffs on a cigarette as she steps out in striped PJ bottoms and slippers out and about in NYC

Maisie Williams puffed on a cigarette as she donned a trendy pink outfit in New York on Thursday.

The actress, 27, wore a pink cardigan over a white T-shirt and wore candy cane striped pajama bottoms and comfy black slippers.

She stood in front of the door of a dilapidated building, holding her phone loosely.

Maisie completed her look with stylish glasses and a straw handbag that she carried in the crook of her arm.

It comes after Maisie revealed she had lost almost two stone (11.79kg) for her latest role in biographical series The New Look.

Maisie plays Catherine Dior, the famous “emaciated” sister of French fashion designer Christian (Ben Mendelsohn) in the series that began in February.

Under the supervision of medical professionals, Maisie revealed Harper’s Bazaar how she “ate very little.” She managed to lose weight, mainly by sweating out fluid just before filming – a technique boxers and jockeys use before competing.

“I had to get up at four in the morning to start sweating,” she explained. “The night before, around 7 or 8 p.m., I was allowed to eat something salty and dehydrating: some smoked salmon and a small glass of wine.

‘Then I was given a boiling hot bath with lots of salts in it. And I kind of drifted off to bed and slept maybe three hours, and woke up and had a handful of nuts.

‘Right now I couldn’t sleep all night. I kept waking up feeling like a marble in a bottle, rattling around…’

The New Look follows Christian in Paris after World War II as he creates his clothing line unofficially dubbed the “New Look.”

The Apple TV show also features his rivalry with the already established Coco Chanel (Juliette Binoche).

The first series had ten episodes and was broadcast on April 3. A second series is already in development.

Maisie is currently single after splitting from her boyfriend of five years, Reuben Selby, in February.

Maisie shared a photo of the pair on her Instagram Story and wrote: ‘The end of an era. Reuben and I have decided to end our relationship.

“Since we met five years ago, our connection has always extended deep into our shared, and separate, creative careers… and it will continue to do so.

‘This decision is something we are so grateful for, or because we can protect the magic that we cannot help but radiate every time we put our brains together.

She added: ‘Ps no further questions please, we have to protect our children (my dog).’

Reuben, 27, is a fashion designer, founder of modeling agency Contact Agency and co-founder of ‘360 creative studio’ Cortex Creatives.
