#Regina returned the dress to the store,which was torn at one of the seams.
ans- Regina returned the dress ,which was torn at one of the seams,to the store
in theory its given that COMMA shall only be used with "which" when its accompanied by a non essentially modifier....(i may be missing some point here but this is not the essential point that i am making)
isn't underlined portion is ESSENTIAL modifier as it is explicitly state which dress she returned,otherwise she may has returned any dress...(this is main point i am stating)
please correct me if i am wrong and please support your answer with example and explanation... which will make it easy for me to understand.
