The neckline has a bearing and possibly the sleeve design. Or is it just a case of it is what you call it? I have a yellow "dress" made of T-shirt type material with a very short sleeve that is knee length and I just don't know what category it comes in. Duh!
I believe this may vary with time and prevailing style.
Generally speaking, today, one gets t-shirts of various types (and I put rugby/polo shirts in that category) which stop pretty much at the hips; they can go longer into the "tunic" length, but are virtually always worn with some form of trouser underneath.
Outright dresses, however, are designed to show off the legs and are certainly
not designed with the idea of wearing trousers under.
Tunics
can go either way, but if one wears a hip-length t-shirt without some cover below it'll be a quick trip to the local lockup.
Mini-dresses are a bit of a special category as they can be shorter than modern tunics, but they are also tailored garments which fit the body whereas the typical tunic doesn't. Mini-dresses also tend to only look good on those of a certain body-type whereas anybody can get away with a tunic.
