All very nice but 2 and 3 are my favorites. The contrast is very nice.

I wore my Halogen with a white tee and a neck scarf...the tee made it casual. Can't help but echo the idea of denim jacket, blouse, or vest.

These outfits looked on the casual side. As others have said , add denim for casualness. You might try a leather or knit moto jacket, maybe with a great graphic tee under it. Also try a striped Chanel-esque tee.
