Long hair envy.
Even though my hair is quite long already, I'm daydreaming of the time when I have long layers. MK circa '07 (?), when she had really long, tousled hair is the main source if inspiration right now. I just need to sit back and wait patiently for my hair to grow!
I also flicker between wanting long hair and chopping it off into a shorter, blunt cut. Hannah-Rose has the same thought. But I've grown my hair for too long for me to cut it all off just yet.
