I have graduation pictures coming up. Help?

I need help deciding what to do with my hair.
I have long thick dark brown hair.
It gets puffy sometimes.
I want my hair to look soo pretty in my grad.
Almost anything looks good with my hair.

I just need help deciding what to do.

Also I’m asking this here cause I ALWAYS get more answers here
I have a CHI.

I’m gonna save the salon for the actual grad.
