In a recent post I explained how to get programming ligratures for the font Operator Mono. Operator Mono also has a very special italic font style which is often and gladly used for comments in code editors.
You can get those fancy italic comments in VS CODE by adding this to your user settings:

"editor.tokenColorCustomizations": {
	"textMateRules": [{
			"scope": "comment",
			"settings": {
					"fontStyle": "italic"
