Do nuns wear perfume I bought a nun at my children's daycare a perfume pack and my sis told me she doesn't think that nuns wear perfume I don't know whether to give it to her now

Not a good choice as a present for a nun of any order. They are not supposed to wear 'adornments' and perfume would not be one of them.

Not sure, maybe I have progressive nuns here in Atlanta, but I have seen them with ear rings, of course cross necklaces.
And yes perfume.

In fact as most don't wear habits any longer it is harder to tell them from just anyone at church. * I always preferred the habits

I will add there are dozens of various ORDERS that they belong to. That will make a large difference.

A better option might be a gift certificate from the place where you got the perfume, so she can choose something she likes and is permitted to use.
