Same shorts, different chamois???

[7rider]

How can the same model have different chamois? I could see if I bought one pair last year, but I bought both this spring. I don't even think they made these last year, so no "old" models could sneak in.
Any ideas?

I have no suggestions either, but that happened to me once.
I bought a pair of Hind bike shorts from an on-line/catalog retailer. I liked the shorts so much, I called up and ordered a second pair - same catalog number, same price, and, supposedly, the same shorts. The shorts that came were very different. They were okay, but definitely not the same.
