This is about as minimalistic and casual as I get. I think I feel that I don't have that inherent aura of 'cool' to be able to pull off really simple looks that other girls look amazing in. Jeans are a rarity for me as well (bar my awesome purple jeans) and I tend to find them restricting, not comfortable as they are widely pronounced to be.

I bought this blazer from H&M when I was in London. It was love at first glance and it has never let me down since.
