No, is the same as saying the two images from the two examples I gave you are the same suits (they are) even though they have some minor differences.

Is the same case as with this image, there are minor differences, which are not enough to say Black Panther was using an old costume.

Following that concept, the concept art image is also old, because in the most recent issues of New Avengers Black Panther hasn't used necklace.
