As it turns out that naked catwalk video I saw wasn’t from How To Look Good Naked but from another UK show with the exact same premise simply called Naked. Specifically episode 2 from season 1 titled Estate Agents. 5 estate agents participate in exercises meant to help with their body image and self esteem.
Unlike How To Look Good Naked however, the only nudity in this show is from the catwalk at the end. They all walk nearly naked, wearing only a robe or shirt and then take it off to show off their bare backsides before going backstage. After they all strut the catwalk individually they return as a group and get completely naked. I don’t know if this is what they have all the women in the show do or if the group was feeling bold. I’m not sure why these women felt insecure about their bodies. They all look great!
Something worth noting is apparently the audience for the catwalk in both of these shows has their friends and family present. Imagine that: you get a phone call and someone says your mom or sister or daughter is going to be naked on TV and want you to be there for it.
