What are the selling points of clothing items

If you have been in a garment company for a long time, you will often hear the word “selling point”.
As long as the commodity department, marketing department, especially the sales department is present to review the version, the word “selling point” may appear dozens of times.
This is also our design department and the sales department, in the review of the version of the controversial.

Then the question arises, the design point, must be the same as the selling point?
