Thank you, everyone for your time and feedback.
Our parish does not have a dress code requiring the First Communicants to wear similar colors/dress. …and yes- where it is my son’s sacramental celebration, my husband and I - as his primary educators of the faith - do guide him and inform him on many matters. Being only 8 years old, he does not know what options are out there for these kinds of celebrations - he is not aware of any arm bands at all (white bows or blue bands). Also - knowing my son, he would not necessarily be keen on the white bow, but would like the blue band - especially as dedicating him to Our Lady on this amazingly special day.
Also, I did speak to our pastor this morning, and he thought a blue armband dedicating my son to Our Blessed Mother was a fantastic idea.

In fact, he wants me to do a write-up describing the arm band and its significance to give it to our school’s Principal and the parish’s Faith Formation director to see make other parents aware of it.
