Can't decide (Vote on your left)

So as part of Ellie's 1st birthday invitations and pictures that will be displayed at her party we are taking special  birthday pictures. As part of the picture I want Ellie to be wearing a 1st birthday hat from  etsy. After looking and searching all morning I have it narrowed down to one seller and a few different hats. I need your help deciding which will look the best. For the pictures she will wear a matching diaper cover and for the party I'll make her a matching number onesie and most likely a black pettiskirt or a mathing one. Not sure on the pettiskirt yet.

Here are the choices:

1)
