The answer is an absolute yes. A denim jacket can be paired even with your summer outfits to amp up the look.  I, personally, love wearing a denim jacket with a breezy dress. It just enhances the beauty of the dress to a whole new level. I’ve mentioned what to wear with a denim jacket in summer for you above, in case you’re looking for inspiration. Also, you can wear a denim jacket when you are going out on cool summer nights. It adds a nice layer of coziness, whether you are going out on a date or simply hanging out with friends.
