We have a few dandies here! I'm perhaps less of a dandy than a dandy aficionado! I love the dandy spirit - and I tend to think that dandies are far more substantial and deep than most people give them credit for.
Let's have some pictures! Show us some "dandywear", people!
For a special event, I will strive for the dandy look -- that is what makes the event so special. Then, I will use a pocket square (which I like in a pouchy style rather than a Don Draper sharp edge... a more bohemian look for me).
For the workday, I strive for "natty" which I see as a low-key version of dandy. I particularly like colourful socks. And I also like a little jacket collar pin, either of my school or a whimsical one.

So far, I did wear either of the two, yet not both at the same time, on certain special occasions.
I quite often wear a pin in combination with a scarf/ascot, apart from my more regular accessories (watch, fragrance etc.).
It is my understanding that the buttonhole is making a comeback, or the jacket collar pin. Ditto for the boutonniere in the form of a carnation or gardenia. This is more geared to weddings, but it shows some choices for boutonnieres.
