The 51-year-old star loves her understated approach to dressing for prestigious events.
"There is a little effort that goes into the planning, like, weeks ago but at this stage, it's only a matter of opening the box," she added.
Swinton has previously spoken about stylists. She doesn't understand why Hollywood stars have their own personal people to dress them.
"You mean there's somebody in your hotel room who actually takes your clothes out of a suitcase and lays them out for you," she mused in an interview.
"Really? Or is that just a fantasy. There is nobody in my suitcase, but myself, I can tell you that."
