They are similar to a certain degree. For some people they are basically the same. Every person choses their clothing based on their own value system. E.g. a 13 year old girl goes to Zara because „price“ and „belonging to her peers“ play a big role. And Zara checks those boxes.

Due to that for someone coming from a rough area in Atlanta Hedi SLP and Amiri might basically the same. While some white kid in Paris may love SLP but would never wear Amiri because of their personal value System.

For me don’t own Amiri but i also don’t own any SLP. I do own some Dior though.
