How to read the price gap
Both are upper-mid in the engine, making price position close. Product-level prices can overlap unevenly, so the more useful difference is how each brand uses that position stylistically.
Where each range is stronger

Who each brand is shaped for
Both target design-conscious shoppers, but Aritzia is more women-specific and practical for polished everyday/professional wardrobes, while COS also addresses men and shoppers seeking minimalist fashion expression.
