sister of groom dresses

Does anyone else find it offensive/extremely inappropriate for the school counselor to ask the females(only females) to send pictures of themselves wearing their graduation/ 8th grade dance dresses?! Apparently this is a measure to be sure they meet the “guidelines”. I can’t believe my ears sister of groom dresses ? . Especially amongst the current climate of anti-sexist/ misogyny movement. This Mom/ Woman is saying HELL NO! Not happening. You will not do this to the women in my family.
