Definitely a case where boys are probably easier and can go with khakis and a polo shirt or khakis and sweater, depending on the time of year.
Are you doing interviews over spring break? I honestly haven’t thought about scheduling, but we may visit one school over break where they just offer a tour and interview (in lieu of an info session), and I am wondering how strenuously to push DS to do an interview, if only for practice 
I too am looking forward to no parent interviews (though I have been included in meetings with coaches) and no parent statement!
