This is a great example of what I meant by discussing how some people choose to view wedding stuff. You see the immediate negative aspect to the concept of mother of the bride and mother of the groom having at least some semblance of overall cohesion to the wedding as getting approval and an immediate thought that this is somehow connected to social media when in fact it's a fairly normal commonplace thing.
My own mother asked me without me even thinking if the dress she planned on wearing was okay and I don't think at all she was thinking "I must ask my daughter for approval" but rather she was employing a time old thing called consideration
