To add to what everyone is saying, being Yekkish is more than just waiting three hours between meat and milk. It’s an attitude, a mindset, and a hashkafa. I find it incredibly sad that there are individuals who think that Minhagei Ashkenaz can be boiled down to a few rote customs that don’t take much conviction to uphold. It’s not just about showing up on time (although that’s part of it). It means being reliable, being consistent. It means being flabbergasted that another yid could possibly cheat, like the famous story of Rav Schwab ZT”L who was asked about a case involving a frum person who committed tax fraud, “Nu? Was he frum or did he cheat on his taxes? You can’t have both!”. It’s Torah Im Derech Eretz, but it’s so much more than that! It’s understanding what it means to view the world through the lens of Torah and not shut yourself away, but appreciate Hashem’s beauty in all the gashmiyus from science to literature. It’s about change, not clinging to “that’s what was always done”, but to not be afraid to move things around if necessity arises. Do you know why we don’t have any Sifrei Halacha from Rav Breuer or Rav Hirsch? Because it’s a big part of Yekkishkeit that things change, and every psak may be only a Hora’as Shoh. What a Rav said fifty years ago may no longer be applicable and shouldn’t be looked at like Torah MiSinai chas v’shalom. It has it’s own way to make a Kiddush Hashem, to show the world the beauty of the Torah by example by following the Torah to be exemplary human beings in the eyes of the world. It’s not about walling Torah off from the world and cultivating it in a small, fenced garden. But about seeing how there are no walls to the Torah, and the only way to truly be a Ben Torah is to see how everything and anything is Torah!
But yeah. Wimples and tallios are nice. That’s what people like. Whatever.
