The MIJs are better quality, fit slimmer and stretch less compared to the MIIs.
So if you paid for MIIs and got MIJs you got a good deal because the Japanese ones cost a little more than the MIIs and they are better quality.
I can't really tell from one picture, but it looks generally OK from the Diors I've seen.
I'm assuming you went with the 21CM not the 19CM?
Hope that helps.
