I think just as much as your house represents who you are, your clothes do the same. Clothes allow you to express yourself and have a story.
Maybe you have a pair of pants splattered in different colored paint that represent the creative projects you've completed over the years (Tuula). Maybe you like to wear a worn flannel shirt that used to be your dad's. Maybe your clothes are covered in spit up...because you are the loving mom of a sweet little bundle of joy.
Whatever your story, share it in a self portrait.
