Well after reading all of this....
I am proud to say I have never heard of "Hollister" jeans.
My children don't ask for specific brand name anything. Exception is Boy 1 that likes a particular brand of jeans - they are not popular or cool jeans, they just fit him better than any other brand and they are not expensive in the least.
Although we do not have a uniform where I work, I am surrounded by professionals earning 6 figures a year and we do have a "dress code" that must be followed.
Most of my 6 figure coworkers, during stressful days, walk around saying "Welcome to Walmart" and "Want fries with that" because to them, those are stressfree joyful jobs. Proof that many humans just aren't happy as long as they have to work, the grass is greener on the other side of the fence (in one's mind), and happiness cannot be bought with a big paycheck.
Boy 1 is on the new dress code committee at high school. They are talking about generic uniforms. It is hard to enforce the dress code when you call the parent because their daughter is in hoochie wear, and the mother walks in to get her wearing an outfit that makes her daughter's look like a nun's habit.
