I love these! From a series by photographer Sophia Vogel called With and Without. Which she summarises (translated from German):

The project and each individual image is intended to encourage society to think about itself, its own body, about acceptance. For diversity and against beauty ideals (advertising) and all the environs for the exterior. I advocate in this work for self-love and acceptance of one’s own body, as well as the acceptance of others with their peculiarities.

It’s also an excellent illustration of the absurdity of our default clothed habits. Even if you’re not able to overcome the wider cultural taboo of nudity, why wear clothes at home when it’s not cold? What purpose do clothes serve when you’re just sat at a computer or watering your plants? You don’t need protection from clothing most of the time. Indeed sometimes, like doing yoga, they’re just a hindrance!
