Not a woman but have traveled a lot and have many friends and family who are immigrants and/or live abroad. Americans are generally way less concerned with specific labels and designers compared to Europeans and people from Latin America, in my experience. We are more likely to have a favorite store than a favorite label. For middle class Americans, it is often seen as frivolous or gauche to flaunt designer labels. It's a bit "new money." Whereas many Europeans of similar means have several designer pieces and would not hesitate to buy (for instance) glasses that say "Prada" across the entire arm. A lot of people also buy off-year or otherwise discounted clothes at places like Nordstrom Rack & TJ Maxx/Marshall's, where you don't expect to see the same labels every time.

The big exceptions are sneakers and activewear. Nike & Adidas have rabid followings, and many popular newer activewear brands like Lululemon are prestige-coded.
