It’s definitely blackout, but not the best blackout curtains I’ve seen. The picture shows the curtains closed with blinds open, so it can get a little darker. But if you don’t have blinds as well then this is what it looks like in the afternoon. This is also with the sun over the house, and not shining on the window. I had gotten two since there is only one curtain per package purchased. Looks really cute in my nursery!
