@Simi_2210_ 18 or 20 depending how you look at it. Each through and through are 2 holes. Front fabric and back fabric. The through and through holes equal 14. Add the neck, torso and arm holes you get 18. If you count where the arms and shoulders meet that would make it 20.
@GTWScar They certainly can. The last few times I've visited any doctor they tried to upsell procedures unrelated to why I was there. I used to be a CSR for a cell phone company. I know an upsell when I hear it.
