What to wear when its cold but summer?

My go to is always layering a leather jacket with distressed denim jeans. While on my travels in Napa the weather would drop at night and I always had to keep my leather jacket handy for when I got cold. Since I was someplace warm ((and on the west coast)) I wanted to blend my east coast edge with a west coast chill look and I paired my boyfriend ripped jeans, which have a bit of a dramatic distress at the knees, with a tight black tank top tucked in and some black booties. 
I also love how a tucked in tank top looks with high waisted jeans – it gives the illusion of a body suit and creates a clean and slimming look!
