I have some Acne tees, knits, scarfs and shoes and I love them all, the quality is also great. The Copy tee especially is a staple in my wardrobe.
BUT, you have to be really careful when buying Acne pieces because they have started to use alot of synthetic materials in their clothing. The price still goes up every season though

For example the Lina knit is 70% acrylic and still the price is 220€. That's just hilarious.
Even H&M sells better materials for a fraction of the price. I believe synthetic can be made to look and feel good too but it's just the principle, I'm not paying that much for a fabric that costs nothing to make. Acrylic doesn't even keep you warm in the winter.
