You clearly see you've outgrown your self when a big chunk of your wardrobe doesn't fit energetically anymore.
When the patterns of your nature have taken root in your inner world and suddenly only solids will do; when the bright colors of your adventures have recalibrated into a galaxy of cosmic shades; when the flurry of the stuff-obsessed doesn't faze you anymore, and only exquisite will do.
Then do just that.
Solid, deep, exquisite.
Wear what fits and suits your soul.
