I think you only looked at the hats from the previous season.
Check below hats from SS13. It doesn't say that their MIU.
And it doesn't say that their MIC as well which I don't think it's fair because most of the people would think Maiden Noir's hats are MIU.
Quality definitely got worse compared to the ones from the past season.
Leather straps are thin and feel so cheap and stitching is terrible.
Shape of the hats changed too. They kinda have this rectangular shapes now.
One of the hats that I bought from this season had a front label stitched up side down.
I was wondering why 3 out of 4 of my hats that I own from this season have such a bad quality...
I checked the care label and it says MIC. Now it all makes sense.
