Kate Hudson gravitates towards comfortable red carpet clothes because she needs to be able to 'express' herself

Kate Hudson "gravitates" towards comfortable red carpet outfits.

The 46-year-old actress has been back in the spotlight on the press tour for her new movie Song Sung Blue - the true story of Neil Diamond tribute act Lightning and Thunder - and she's revealed the outfits were picked with the help of her longtime stylist Sophie Lopez with the pair opting for dazzling designs by Valentino, Stella McCartney, Fendi and Dolce and Gabbana.

Kate told PEOPLE of the collaboration: "I trust that not only does she intimately know my fashion sensibility, but that she pushes me as well, and because we are so close, it makes the process of dressing up and the choices that we make a fun and easy experience.

"We both love fashion and find it one of the great artistic expressions, and we enjoy telling stories through clothes. I feel so lucky to have her as a friend and a collaborator."

However, Kate admitted the options she picks tend to be the more comfortable options, saying: "The things that I usually gravitate towards and have always gravitated towards are things that feel effortless and have a sense of ease and comfortability that allow me to move freely and express myself freely while wearing beautiful garments."
