What can I wear with a blazer?

Well it all depends on what color and style blazer. I bought an off white one from Forever21 that rolls up at the sleeves and has pin-stripes on the cuffs and pocket flaps with a big on on it but no actual pockets. The blazer is longer, like down to my bum. I wore it with white jeans one time and a darker tan top and heels. I wore it another time with a sequenced black top and black leggins. I'm in lovee with it!
