It is easier to answer the question the way you worded it than the other way around. Finding a list of items that will get you kicked out of a plane probably depends on local customs and the pilot's mood!
What will not have you kicked out of a plane is easier. For men, trousers without holes which cover entirely undergarments. A woman can wear pants too but long skirts are acceptable. In many places one can go shorter but if you are connecting through some more religious countries, keep it below the knees.
Wearing a top which covers your upper body, including the shoulders also not get you kicked off the plane unless it is transparent or features offensive words or imagery. Even if you transit through some country where women cover their hair, a tourist is rarely asked to do with on the plane or in the airport.
As for examples that will get out. This will vary greatly, if you take a charter flight to beach destinations for example, you will often see people in shorts and bikini tops. In many other I areas, I suspect this be enough to get kicked out. Very shear materials or belly-tops are also likely to be frowned upon.
