I have searched Mi Yodeya and see a few questions on this topic but I do not feel as if this basic one has been answered. I am curious if it is halachically permissible to wear 2, or 3, etc. garments, each one with Tzitzit strings.
I want to explain why I think the other questions here are not duplicates.
This question discusses whether one should wear multiple. I am curious if it's allowed. Further, the answer there discusses whether or not it is proper but does not say whether it is assur.
This question seems to refer to the Heavenly reward conveyed for two pairs, and the comment by DoubleAA seems to say that is is assur to do. However, I am unclear on whether he is referring to more than 4 strings, or more than 1 garment.
So, while there are three questions on this sitre that seem to pertain to this idea, I am seeing different ideas on whether it is muttar or assur to do, based on those comments and answers. My question, which I think is diofferent from those, or at least has not been answered in those, is whether anyone has asked a Halachic authority, or they have seen a Teshuva or Psak, that wearing multiple garments with Tzitzit strings, al pi halacha, is okay to do.
