How to wear a denim jacket?

[Justkoko]

In summer, over dresses with bare legs, great.
In cooler weather...what? I wear jeans all the time and double denim feels weird! How can I dress for a casual night out? Black jeans OK?

I've got a darker denim jacket for autumn that i wear over wool dresses or winter maxi dresses. Layer up for warm-vest, nude tights underneath, big scarf, hat. Yes to black jeans or get a black jacket to go with blue denim.

jersey green dress from H&M with knee high boots looks lovely with a denim jacket.
