to add onto the shoulder thing. big woolly sweaters usually hide your shoulders pretty well.
I personally don't like hair accessories like in OP's pic. Buttoned clothing is cool. For shoes, I like sneakers or boots (as long as they don't look too classy). For coloring you should probably go for pastel-type things. That means no fully saturated colors (like pure red, green, blue, yellow, etc.) unless it's summer.
See what you like for yourself. I don't really like a lot of female clothing because it's usually very fiddly with a lot of bells and whistles, but there's usually some nice stuff there too.
Try different stuff out. Develop a taste for things.
