Every now and again, people will ask me what the difference is between denim and chambray, since both seem to look pretty similar. Well my friends, today I shall reveal the difference, and fingers crossed that you don't leave here more confused than when you entered.
Alright, so the picture above shows you a denim jacket and a chambray shirt (though I'm using a bad example of a chambray shirt here since it has a herringbone design). Generally, this is how you'll see denim and chambray used: denim for jackets and pants, chambray for shirts. However, it's important to note that this isn't always the case. Denim can occasionally come in shirt form and chambray can be used for jackets.
Anyhow, the main difference between the two is in the way that they are woven. Denim is woven diagonally, while chambray is plainly woven, meaning that there's more of a traditional criss-cross weaving happening. The best way to tell is actually by looking on the inside of your jeans. Since they're probably made of denim, you'll notice the fabric is woven diagonally. This weave will look very different on chambray.
So in all, clearly not that big of a difference between the two. And perhaps a rather boring difference if anything. Either way, I wanted to at least clear up any confusion. Alright, getting' out of here, happy day before the 4th!
