Michelle Williams liked wearing 'toilet' dresses

Michelle Williams has revealed that she enjoyed wearing long dresses for her role in Meek's Cutoff as it allowed her to go to the toilet easily.

The Blue Valentine actress wore period costumes for the film, which focuses on settlers travelling through the Oregon desert in 1845 who then find themselves stranded in harsh conditions.

She explained to Interview: "The dresses, they were ingenious for so many reasons. They actually do keep you quite cool, because they're cotton, and they also provide cover. Privacy is important to women, and when you're on the trail like that, so little is afforded.

"But with the dress, you can actually go to the bathroom in private. It provides an incredible shield. You could literally be in a conversation with somebody and just sort of drop down. I can't believe I'm talking about this."

The 30-year-old said that she liked the outfits that she had to wear so much that she and her co-star Zoe Kazan went out and bought some when they had finished shooting.

She explained: "It's like wearing blinders, really. But again, the lack of privacy on the trail almost created a sense of privacy when there is none. Zoe Kazan and I became close during the movie, and we missed our bonnets. I missed the whole thing.

"There were two Winnebagos that housed hair and make-up, wardrobe, ADs, changing, everything... and we'd take our dresses off at night and I'd catch a glimpse of Zoe's ankle, and it became like pornography. When you're covered from head to toe all day long, you're not used to the sight of skin, and I would sort of avert my eyes because I'd feel like I was seeing something inappropriate.

"But we bought bonnets. We've been threatening each other to wear them in Brooklyn, but so far neither of us have been bold enough to break them out."

Williams recently confessed that she grew up fantasising about living on her own.
