Q. Dear Honorable Rabbi,
I came across a colorful wool taalis that was made for a lady to wear (I guess reform or something) is it permissible for a man to wear or is it considered a woman’s garment? Furthermore is it an issue in regards to it being unknown if it was made lishma?
Q. If you install new long kasher tzitzis, does that turn it into a man’s taalis that one can wear?

A. Indeed it the taalis was made for women, a man would be forbidden to wear it due to the “lo ilbash” proscription of a man not wearing a woman’s cloth. Furthermore, if the taalis belongs to him, he would add the prohibition of wearing a four cornered garment without tzitzis, since the ones attached are pasul and unfit.
Horav Shlomo Miller’s Shlit’a opinion is that even if one would place new long kosher tzitzis, one would be still prohibited to wear it, since it was created as an act of transgression.
