McConaughey, 42, said he was keen to keep the leather trousers and vast array of thongs that his alter-ego has to wear during the film, reported Contactmusic.
"I kept all mine. As soon as we found the leather pants on the first day with Christopher, the costume designer, we were like, 'Okay, that's Dallas's staple,'" he said.
McConaughey, who stars alongside Channing Tatum, Alex Pettyfer and Olivia Munn in the comedy film, said that he was very nervous ahead of his first stripping scene.
"I was very nervous, yeah. Before going out on the stage, to dance, even if you're not taking your clothes off, for everyone live is kind of nerve racking, but then knowing you have to strip down, very nerve racking. Then after doing it once, God, I wanted to get up there and do it again. That was a lot of fun."
