When I cut mine too short, I look like I'm 12 (because I have a babyface and because I'm fat lols).

When I have it mid-length, I look like a butch lesbian.

When its about to the bridge of my nose (my bangs, I keep all my hair the same length) thats when I think its best. Is this what you mean?

I'm trying to remember what I told my hair cutter person. I haven't gone to get it professionally done in like 5 years, I always just cut it myself. Just ask for a trim because you want to keep it long I guess.
