TurtleShroom's educational system recieves a ton of funding. However, uniforms are one of the least-funded items.
In public schools, elementary, middle, and high allow their students to wear what they want (as long as they are wearing something appropriate), but are mandated to wear black floor-length robes over that,
except in gym.
Hoods are optional, and each student decides on that, but they have become increasingly popular because of the- well, you know -
gangsta fad.
The robes are provided by the school.
Private schools, however, are free to make their own rules.
In college, all male humans wear this:
The cane and top hat are not included (or mandated), but the greatcoat, belt, and pants are provided (a T-shirt or other garment can and should be worn underneath since the coats can be scratchy). Male humans are also allowed to wear shoes of their choice with this uniform, but sandals must have backs. The most popular shoes are sneakers, especially those brand-name ones, athletic shoes, and Nike. The national seal of TurtleShroom is sewn onto the greatcoat where one would normally expect a crest/logo to be.
Female humans' dress codes are not written in stone, but they are expected to not show any cleavage and their skirts or pants must be at least to their kneecaps
As for hair, both male and female humans can do anything they want with their hair. This includes color, dye, spiky-hair, and hair covering one eye (scene/emo/in-style hair). They can even opt-out of having hair at all by being bald. The only requirement is that when a teacher speaks to them, students with long/scene/emo/whatever hair that obstructs their eyes must simply move the hair out of the way, to give the teacher respectful eye contact. That can be difficult for human students at times, because they may have to look down at a turtle or mushroom teacher.
Students are allowed to wear various accessories, but because of the lingering Southern Baptist and conservative-syle traditions (no dancing/drinking/gambling heritage), male humans can not pierce their bodies. Female humans may pierce their ears, if they so desire, but only once and on the earlobe. Earrings may be anything that isn't considered "unholy" by the school (e.g. skulls, alcohol bottles, pentagrams), no size is mandated.
Students may wear jewelry over their robes, greatcoats, or other garment, but the pendant/meddallion must be considered "holy" by the school. As such, most "bling" consists of oversized golden crosses, shapes, and other generic symbols. The medallion can be as large as the student desires, but it must remain on their bodies and it must hang no lower than their chest. If queried on what their jewelry/ring/necklace/bling/whatever means, the student must tell the teacher immediantly.
Total nudity in school can result in harsh suspensions and corporal punishment (paddling), or both. Not wearing the uniform results in detention.
Students are also allowed to wear whatever religiously mandated garments they need to in school, even if it overrides the school uniform. Of course, this excludes parody religions, Pastafarianism, and Satanism (though the black robes that serve as the uniform worn by K-12 worry some superstitious elders). It is not at all uncommon for creatures to be seen wear burqas, veils, necklaces, etc., but loopholes are endlessly exploited. One girl came to school in nothing but a thin bikini "for religious reasons". She was paddled because everyone knew that no religion dictated "thou shalt wear thin, waterproof garments".
Teachers lack a dress code, but they must wear clothing, shoes, and apparel appropriate for school.
