This hat is a very girly girl type of hat but you can always tone it down by just making them pom poms, or just making the flower. I also want to say use this pattern with good judgement, it is a preemie hat. So if you believe it may be too heavy just use the pom poms or flower. But if you love the combination of the pom poms and flower, you can also make a one layer flower and small pom poms.
