What was your gateway?

Hi sunglass Redditors. This may have been covered before... but I'm wondering what was the gateway pair of glasses that got you hooked? For me it was my Randolph aviators in Le Mans blue that I bought a few months ago. Since then I've been incrementally upping my sunglass game. For years I've been an Oakley and Smith wearer (and I still love and use those glasses), but once I picked up a truly great pair of glasses It's hard to go back. So what was your gateway pair? What is a certain frame that you love, or a certain lens? Maybe a combination of both that brought your interest into sunglasses to a different level than before? Let me know. I thought this would make for an interesting thread.
