I'm wanting bra strap length, personally. I want my hair long, but so long it's unmanageable. At that length I can have a nice long ponytail or braids that aren't too short. My last haircut was about 9-10 months ago (jarhead cut, before I accepted being trans), and my bangs are just now reaching my cheekbone. It seems to be at this length that no matter what I do, it doesn't look very good. But I know that will pass.
