I found a lot of tips for the 'badboy' seducer on this Reddit, but I'm currently looking to portray the 'classy' vibe more ( when we're out ), to embody that sort of fantasy. A more polished persona, the guy wearing shirts / suits, going to classical music concertos, operas, taking her out to fancy diners and similar things - but from a seduction POV. Where's a good place to start? Books / guides / movies?. Appreciated.

Edit: To make it clear, I'm into that shit myself, and I'm doing it mostly for my own benefit, not just to impress others for seduction/hookup. Thanks.
