Heels over 2 inches (so...pretty much heels in general)
I already have a battle with gravity when I've got at least a slight bit of elevation in my shoes, so there's no point of me wearing heels when I have to dress up. Honestly I'm really glad I changed from being a teacher to being a nurse. Nurses don't have to wear heels.

Skirts
When I was 15, I was extremely fat in the legs, and got made fun of by nearly EVERYONE about it, so now I refuse to wear anything that shows any leg. So skirts of any kind don't cut it. Hell, anything longer than a short skirt looks like an old lady's wardrobe anyway.
Ridiculously tight shirts
I don't like people being able to see my stomach through my shirt, because anything tight like this, it totally sticks out. I mean, not grossly "shirt rides up and exposes my belly constantly" tight, but still.

Shorts of any kind
See Skirts for explanation. Same thing.

Turtle-Necks
I cannot have anything touching my neck. Period. It makes me feel like I'm choking.
And of course, the above mentioned Visor that needs no explanation.
