Very nice minimalist design with the off white shirt design

I first purchased this in April, and it became my favorite t-shirt: perfect fit, great weight, nice material, cool badge. Then I tried to order it again in June--in the same size, obviously. Guess what? It was like a whole size bigger. And the color also changed from ivory to some weird yellowish tint. Adidas, what is going on? Look at the photo where I placed the April version on top of the June version. I even double-checked the size on the label. Fit and length score are for the June version.
