Oh geez... so many to pick from.
* No one should be orange. No one.
* I agree with the blue eyeshadow. Unless it's fantasy makeup, leave it at the drugstore.
* Lip liner that does not match your lipstick
* Glitter. Only exception: New Years Eve, or some other festive occasion. Like Halloween.
* Not everyone can be a blonde.
* Along the same route, If you have orange hair, you are not a blonde. Learn how to properly dye your hair, or go to a professional.
* Overdone. ie: strong eyes and lips. Pick one. Stick to it.
* Overly lined eyes. Makes me think of a raccoon. My mom will often do this when she's getting ready for a night on the town. I affectionatly call her "Bandit".
* Clumpy mascara
* Drawing on eyebrows
