Actress Emma Watson is changing the way she dresses because she hates feeling uncomfortable during nights out.

The Harry Potter star is a keen follower of fashion, but she has grown sick of wearing painful high-heeled shoes and super-tight dresses, so she has vowed to put comfort first in future.

"When I was younger I remember being told 'no pain no gain', but recently my willingness to wear something that makes me freezing cold or that I can't walk in has changed..." she tells Porter magazine.

"I want to feel fabulous and comfortable and sexy and strong and beautiful. And if it's making you uncomfortable, don't do it. It's so sad if you need to go home just because you need to sit down! Moving forward, I'm prioritizing just feeling awesome."

Emma goes on to talk about the #HeForShe gender equality drive she launched at the U.N. headquarters in New York in September, 2014, insisting feminism and fashion should go hand-in-hand.

"I think using fashion as a means of expression is brilliant," she adds. "One of the ways I became a U.N. Women Goodwill Ambassador was through my interest in fair-trade fashion. Because so many women design and make the clothes we wear, it's primarily the working conditions of women that are affected by the decisions we make, so fashion is a feminist issue."

During the interview, Emma also discusses her career ambitions, and cites fellow British actress and Harry Potter co-star Emma Thompson as her inspiration.

"It sounds like a ridiculous thing to say, but I'm very interested in truth, in finding ways to be messy and unsure and flawed and incredible and great and my fullest self, all wrapped into one," she says. "When you watch the work of someone like actress Emma Thompson, you feel like you're seeing something true, and I aspire to that," she tells Porter magazine.

The pair met on the set of the wizard films when the 56-year-old Hollywood veteran was cast as Hogwarts teacher Sybill Trelawney in the movie franchise.
