This varies by council and conference.

In the NPHC, alumnae/alumni wear symbols/letters anywhere the organization's protocol doesn't prohibit. The key is understanding that symbols/letters include but are not limited to 'nalia tshirts. If it can be done in a grown folks style, NPHCers do it until the dayyyyyyy weeeeeee dieeeeeeeee.

ETA: I am not saying that there are no variations within councils and conferences; or that the NPHC is the only council or conference in which members tend to wear symbols/letters as alumnae/alumni.
