I feel like I look best with a 1.5 to 2 day stubble. 3 is unseemly.
I had a TA in college that always had a stubble that was just perfect, it made him look so very cool. But I had no idea how he did it, because he had to shave sometime, ya know? I tried shaving at bedtime, but that doesn't work... his was longer.
