What should i wear with this denim jacket?

I have this cute, light light blue, over-sized denim jacket that I bought just recently from Zara! It's over-sized, but also fits in the right places. I don't want to pair it with Jeans, however it's a bit chilly and rainy, as usual. What bottoms and tops should I pair it with? I also plan to wear gladiator sandals with the outfit.
