Very, very carefully!

Someone tell us what the number is for the 85/1.4. It's ridiculously
small.

Well...like anything else it's a toss up. Due to the DOF, not everything
is going to be in focus, but you learn quickly which parts matter. For
portraits, generally it's the eyes.

Many people, myself included, like a really short DOF when doing
portraits. A short DOF gives a photo a certain 'look' that sometimes
works. Also, it helps to obscure stuff you're not really interested in
showing.

Here's some examples:
