the schools here do not have uniforms.
The dress codes for the students are:
no spaghetti straps(wide tank tops are fine)
bottoms & tops must touch
nothing with profanity, alcohol, drugs
flip flops are discouraged for GOOD REASON!
Teachers "dress code" is business-casual. Fridays it's casual most wear jeans. During M-Th the men will wear khaki type pants or shorts, polo, sweater, button up shirt or a nice t-shirt. The women will wear pants, capris, shorts, skirts(above knee or lower), a blouse, nice tank tops(wide strap, very few will wear a spaghetti strap), sweater, nice t-shirt. For shoes they wear dress shoes, high heels(not usually the men,lol), runners, sandles, flip flops.
Ties are only worn by the men IF it is a parent-teacher interview or if the man is over the age fo 50.
Flip flops - there is a HUGE difference between a child in school wearing flip flops and an adult in school wearing flip flops.
First if the child is wearing them IN the school they are not wearing proper gym shoes during gym time(unless the school has seperate gym shoes in addition to indoor school shoes which usually doesn't happen until middle-high school). Teachers are not usually participating in gym, if they are they will usually bring runners to wear in the gym & take off the flip flops/high heels(which would be worse in gym than flip flops unless you like broken/sprained ankles)
Second & more important. If the child is wearing flip flops TO school they are wearing them outside too. Flip flops during recess time are dangerous. Spend 1 week as a supervisor in a school & you'll realize how many injuries happen becuase students are wearing flip flops outside. Toes are stepped on(can happen inside too), toes are stubbed on things more easily, toes are cut or stabbed with loose twigs, rocks, bark chips, glass, etc. Flip flops come off very easily when running & can lead to injury. When playing on playground equipment flip flops are slippery & cause kids to slip off & get hurt. Croc type shoes are just as bad for this.
Teachers are not doing the same things the kids are outside so they can wear flip flops.
In the schools here the Aides/Paras/Assistants don't really have a dress code. When I'm subbing in some schools I'll dress business-casual. In my main job I wear yoga pants & other workout gear, capris, t-shirts, jeans most days, runners, tank tops, sandles, bunny hug(hooded sweatshirt). I have some clothes that have paint on them in a couple of spots. My hair is always pulled back in a faux bun. I never wear make up more than a light dusting of foundation powder.
IMO if the kid I work with(close up, one-on-one, lots of hand-over-hand) can show up to school with feces on his hands, face & hair, smelling like he's peed all over himself for 1 week with no bath, or reeking like maple syrup(which is almost worse than the pee smell), food all over his face & clothes, his hands, legs, feet covered in warts no way am I dressing up to work with him.
I have worn tank tops with skinnier straps but I always have a sweater of some sort with me so I only take it off if we go outside & it's hot. Our school is either hot or cold there is rarely the in between.
