I think this is ridiculous and over the top. The logo is for “internal use only”. It is not for others to scrutinize. The uniform is exactly for the purpose of “uniformity” and not for you or anyone necessarily to recognize which school a child belongs to. That is a result of schools using the same uniforms year after year.
If you saw someone wearing an interesting belt with a logo on it or a decoration on it, would you go closer and yet closer to get a better look to see what it was or who the designer was. Is it really your business or do you really need to know? NO you don’t and if you did it would really be chutzpa. So it does NOT matter where the logo is. It is on a pocket and wherever that pocket lands on the shirt of the girl depending on the size and the height of the girl it is not your business and it is NOT a tznius issue. It is common that logos, initials, decorations go on a pocket of a shirt. Lets NOT look for problems where they don’t exist. Maybe girls should be required to only wear sweatshirts so they will never draw attention to their private parts. Maybe they should never wear necklaces because someone might look closer and actually zoom in on their chest.
When does this nonsense end?
