There are choices for coat pockets and trouser pockets buttons and linings.
For a single breast there is the common notch, or for the adventurous possibly a default peak.
that default peak will be what the pattern maker thinks looks good, possibly what you would not choose.
But are these the only choices? If its a m2m garment that may be so, but not for the custom tailor.
Now I should take that back, some of the better m2m shops may offer "some" lapel options..
