Here's some dressier outfits in increasing levels of formality. I know the OP was looking for modern looks and I did my best to look nice without being too traditional... the more formal I went, the more traditional the look ends up being.
Hef: smoking jacket and playboy logos.
Slick: if I went clubbing in a kilt I might wear this, though that's kind of a big "if."
Sweater: a little bit dressy.
Spencer: jacket worn without a tie and the shirt collar on top of the lapels.
Sports coat: another jacket without a tie but the shirt collar inside the lapels.
Collarless: waistcoat and collarless shirt.
Dressy: blue shirt, tie, hose, and flashes for that limited palette, modern look. I think ties and kilts look better with a waistcoat.
Very Dressy: same as above but with a Spencer jacket.
Thanks to my lass Bee for taking all these pictures of me and tying that big fat Windsor knot on my tie in the last two
