Double denim, back in style. It's a tricky style to get right but once you do, it looks amazing.
There are good double denims and bad double denims like that of Britney Spears and Justin Timberlake back when they were dating.
Matching denim jackets or shirts with jeans, skirts or shorts is the way to do it. It's best to wear dark denim on the bottom of the body and light denim on the top half. And to accommodate the outfit its better to wear pumps and never boots, cutting off the skin colour on your feet makes the outfit very dark.

And I know some of these aren't double denim but the outfits themselves are amazing.
