Saoirse Ronan arrives at the Oscars 2018 red carpetTwitter

Saoirse Ronan debuts a new blunt bob on the red carpet, leaving her elegant powder pink dress do the talking.

The 23-year-old is wearing a custom-made Calvin Klein By Appointment gown, paired with a monochromatic satin pump.

The Carlow native's star stylist Elizabeth Saltzman had previously teased that the dress was inspired by "1980's Debbie Harry".

Saltzman told W Magazine that she was delighted to work with the Oscar-nominated actress for another awards season.

“She’s the oldest, most wonderful soul that I’ve been fortunate enough to meet. I met her at 21 and she was far older than I was at 50 and wiser, smarter, and cooler," she told the outlet.

“Now at 23, she has the confidence to try things. Her body has changed. Her attitude has changed. She’s all grown up,” Saltzman added.

Ronan's Dublin-based stylist and childhood friend Grace Moore, who looks after the A-lister's day to day looks, took to social media to wish her good luck.
