NTA and not a lawyer. Applicable section is as follows:
New York State Penal Law Section 270.20:

§ 270.20 Unlawful wearing of body armor.

1. A person is guilty of the unlawful wearing of body armor when acting either alone or with one or more other persons he commits any violent felony offense defined in section 70.02 while possessing a firearm, rifle or shotgun and in the course of and in furtherance of such crime he or she wears body armor.

2. For the purposes of this section "body armor" means any product that is a personal protective body covering intended to protect against gunfire, regardless of whether such product is to be worn alone or is sold as a complement to another product or garment. The unlawful wearing of body armor is a class E felony.

Then see 270.21 regarding purchase of body armor.

§ 270.21 Unlawful purchase of body armor.

A person is guilty of the unlawful purchase of body armor when, not being engaged or employed in an eligible profession, they knowingly purchase or take possession of body armor, as such term is defined in subdivision two of section 270.20 of this article. This section shall not apply to individuals or entities engaged or employed in eligible professions, which shall include police officers as defined in section 1.20 of the criminal procedure law, peace officers as defined in section 2.10 of the criminal procedure law, persons in military service in the state of New York or military or other service for the United States, and such other professions designated by the department of state in accordance with section one hundred forty-four-a of the executive law. Unlawful purchase of body armor is a class A misdemeanor for a first offense and a class E felony for any subsequent offense.

In short, the rules are pretty tight. You can thank pic related dipshit for that.
