here are some example pics of what I usually wear.
Example 1, informal:

Fiberops raw denim, 10 Deep tshirt and Penfield flannel! Feel comfortable in this type of combo. I wear this kind of stuff almost all the time.
Example 2, slightly more formal:

Mishka grey denim, S.N.S Herning knitted cardigan with some sort of color accent tshirt underneath. Love this as well but does look a bit more grown up than the tee and shirt combo.
Example 3, trying too hard:

Bought this Staple shirt a long time ago and haven't really worn it outside the house yet, I can't really pull the look off.
