Help With Mustard Yellow Pants

I bought these yellow pants the other day since they were pretty cute and different from what I usually get. Only thing is I don't know what to wear with them! I have a few shirts that would go with these pants but they aren't school appropriate. I've been homeschooled since the 6th grade so being school appropriate is new to me (I'm going to the 12th)

I have this one shirt that might work but something feels off? (please excuse the mirror my brother likes to splash water)
