Ham it up!! There are so many cute outfits for kids. There is no shortage of fun outfits for them! While for the adults I suggest keeping the colors neutral, I don’t feel the same about kids. They have giant personalities, and I love for that to be reflected in what they’re wearing.
The one thing I do recommend staying away from are thick bold stripes. They tend to be really distracting in a photo. Otherwise, just about anything goes! Bow ties, cute hats, overalls, floral dresses. The options are quite literally endless.
