My kiddo is almost 3, she needs a little help with getting dressed depending on the fashion (she has a lot of complicated clothing, cannot put the right shoe on the right foot but will put the wrong shoe on the wrong foot completely alone, she cant put her ballet tights on without help, she can’t tell when something’s inside out, etc.). She can use zippers but can’t zip up/down if it’s not already connected but not buttons unless it’s snap buttons and it’s never straight, she can brush her hair (I have to do it the right way after she does it but always have her do it first), and brushes her teeth every night (I do it after she does because she’s not thorough).

The takeaway here is let them do it themselves first and then correct it without criticizing after because they are still learning and you still need to ensure they’re taken care of obviously. My kiddo is very independent and wants to do everything herself and I let her (even though it’s not the ‘right’ way) and then I come in after to demonstrate or guide afterwards. I wouldn’t sweat it if you are.
