Recreating Pants from the Movie Pitch Perfect

I fell in love with the pants the main character played by Anna Kendrick was wearing in the final scene of the movie Pitch Perfect.  I LOVED the buttons on both sides.

I searched and searched online, but I couldn't find good pants like this, so I decided to try to make a pair myself.  I started with an old pattern I've had for a long time as a base, and then created my own pattern with a number of modifications.

I had to cut the front waistband out twice to get it right, but I eventually achieved an approximation I'm happy with.
