Is there a way to have an object's weight identical to anothers?

Hey, Im working on some low poly characters, and want to model some basic clothing for them as seperate objects as opposed to having the clothes part of the character model itself, as this would allow for a lot more flexability in clothing design. My problem is when it comes to weighting the clothes for animation, the weights are slightly different then the underlying body, and as a result, tearing occurs. Is there a way so that the clothing for the characters has identical influence as the underlying body, so that they move in sync with no tearing?
