As for hoodies if I remember they first were being banned because blacks like to wear them when they commit crimes which made white kids wear them.
Back in the 1970's, before the two sensationalized incidents in the second decade of the 21st Century that spawned the canard you mention, "Hoodies" were not permitted by dress codes in schools because they have no collar. All of the school dress codes I am aware of require both boys & girls to wear a shirt with a collar.
When I was a kid in the 1970's we were allowed to wear a hoodie to school as a light jacket, but then had to hang it up, or put it in our locker.
The thing that pisses me off the most is it is hard to find a sweatshirt that doesn't have a hoody because I hate wearing hoodies.
If you are in the USA or Canada, I recommend Costco or Walmart. REI, Fred Meyer, Target, Eddie Bauer, and Goodwill are all places that sell sweatshirts (without hoodies).
I usually have to buy one or two a year because I wear them for volunteer work where I get them filthy or torn. Walmart or Goodwill are great for inexpensive sweatshirts. REI or Target are better if you want better quality but have to pay more.
May I suggest an alternative? Try an "Army Surplus" store or places such as Quantico Tactical (near several military bases), or similar stores look for "Fleece Shirts" they come in several weights and textures. I prefer them to sweatshirts, but I don't want to get them filthy or damaged, so, that's why I still get sweatshirts. Most "fleece" shirts are designed to be loose fitting and to be used as a part of a layered system. Most fleece shirts or jackets are not good against wind, and in particular rain; fleece are designed to be worn under a Gore-Tex "shell" (jacket). Fleece shirts/jackets are so popular in the armed forces that the term "Fleece Mafia" was in vouge for a while (probably because earlier versions had no rank nor name tape. Senior officers had a "Hissy Fit" and newer versions of fleece were produced that the velcro Rank tabs and name tapes could be attached to.
Polypropylene (or Microfiber) shirts are another alternative, they are more form fitting, and are perhaps more similar to a sweatshirt. In fact, they are designed to "wick" sweat from you to an outer layer (many "modern" versions are one piece not requiring the layers as in the "ancient past" of the 1980's & 1990's).
