How to look dressy, but still feel causal

Tonight is my aunts pageant and I needed to dress up. When I dress up I want to feel fancy, but comfortable at the same time. To achieve this feeling I chose to wear slim chinos, but pressed them to give that dressy look. Then I wore a button-down shirt, dressed it up with a cardigan on top that looks like a vest and then finally put a blazer over it to give an overall “dressed up” effect. Also I added a dressy touch with some dress loafers, but with no socks.
Happy “fancy dressing”
