Headbands and bows leave marks

So I have a 5 week old and it seems as though all headbands and bows leave marks on her head. They are not too tight. The marks always disappear within 10-15 minutes after removal and she never seems uncomfortable. Is this ok? She gets the same marks like where her clothes sit, diaper sits, just leaning up against my shirt etc so maybe she just had sensitive skin? This is the mark after 2 hours of wearing the bow also pictured. Again it doesn't seem like it's too tight it goes on easy. I just clipped the flower to the plain elastic crochet band from hobby lobby. It just leaves like the pattern of the stitching on her head. Is the bow too low maybe?
