In all fashion seriousness though, my desire is to have timeless pieces that can be styled in a fashion forward way and will last a long time. That's why I really love ACNE. I feel like their clothing spans age groups, and can be easily dressed up OR down.
Think about it, you can add chunky jewelry and a fur vest to make it feel younger or add nothing to appear more mature and sophisticated. You can also add a leather jacket and motorcycle boots to look causal or strappy heels and cocktail rings for a night out.
ACNE also does a great job about thinking of the functionality of their clothing. The fabrics are quality, the cuts are comfortable, and there's always a designer detail touch suck as an asymmetric zipper to give a piece an edge.
This clothing brand gets overlooked, but I encourage you to check out their fall collection! I especially like to view designer clothes on my-wardrobe.com because they show items by themselves, as well as in a styled look.
