I purchased this hat for myself (an adult).  I was a bit hesitant to order as the girl in the picture looks like a teenager and I was afraid it might not fit me.  However, it does fit perfectly on my head and I think that because of it's shape it would fit on both smaller and larger heads as well.  The color of the hat was a pictured.  The only thing I would add, is that whatever is giving the hat it's shape doesn't appear to be super heavy weight so you will need to be careful with this product that nothing squishes it.
