Question:
should someone who doesnt wear a talsi gadol do atife with a talis gadol
Answer:
Hello,
You most probably mean to ask if it done with a tallis katan. The custom among the Ashkenzim, who are the ones who don’t wear a tallis gadol until they get married) is not to do atifa on a tallis katan. See Magen Avrohom O:CH 8-4
