While clothing is an accessory and the focus is on you in a picture, remember it still maters! Even if you have a FAVORITE shirt/outfit but it's "showing it's age" that will really come across in pictures. If you have been wearing it for years chances are it's been washed beyond it's life cycle for print. That faded look is ok sometimes but if the shirt was black and is now turning gray or the edges are not so crisp & the seems are coming out...not the best look. And if you have an outfit that "used" to fit like a glove...but a few years later it's pinching in a few spots, that will most likely show. Don't spend time in your shoot trying to hide the flaws in your clothes, spend it looking fabulous and having a blast!
