obviously this isn’t revolutionary but if you’re wanting a more formal look this is an easy win . i’m partial to a tie with a bit of texture vs a flat weave , a grenadine or a silk knit is great for this , it adds some depth & interest to the outfit without being too loud . if you are more of a pattern person i think a navy & burgundy/wine combo could be nice , there’s one here in a flat silk weave & here’s a beautiful navy & brown stripe
i’d pair any of these ties with a navy sock to bring it together .
also take a look at the stores & see if anything else catches your eye & i’d especially recommend wearing the shirt & jacket one day & just going to try some things on wherever they have ties near you
