HELPPP! Which button??

This is a scarf or shawl with pockets I've been working on since last weekend for one of my child's teachers.

I can't decide which button to put on the pockets??

The last picture is what the end product looks like, minus the buttons of course.

Thanks any and all feedback is greatly appreciated, not just about the buttons!

I kinda wanted to extend the length off the bottom of the pockets a little more. Just for the simple fact that she is a bigger lady.
