By attempting to be 'unconstrained' from fashion, OP has become more constrained than ever. Is she saving time & money? Maybe...but that blog post and graphics sure took some time to put together.
And now that she's made this public, she's stuck. Want to wear something different, colorful, playful? Fuck it, gotta stick to the schedule.
Clothing isn't time consuming or energy draining. It's about finding a style you're comfortable with, wearing it with confidence, and gently moving in and out of new styles as the times (and your personality) change.
