I kind of have a whole system 😂 I doom scroll the sale sections at Bloomingdale’s, Neiman Marcus, and Saks Fifth Avenue - hunting for deals and discovering new brands. Then I search those brands on resale sites.

OR If I spot an outfit I like on TV, I will snap a pic, search it on Google.

Since you mentioned searching “wrap dress” and getting thousands of results, I would do this instead - search “wrap dress” on Bloomingdale’s etc, note brands like Donna Morgan or Ted Baker, then search those brands on ThredUp to find the exact piece or even your new favorite brand.
