sorry, that’s incorrect- ghararas have a lot more gheyr than a sharara and that is why they are considered more regal and elegant- because of the way the gheyr flows. its sort of meant to look like an a-line ball gown… that is why the vintage gharara’s you see people re-wearing from their great-grandmothers look so royal and graceful. they had a lot of gheyr.
this is a gharara-

these pictures show the gheyr better -
in a farshi gharara, the two-legged split and the gheyr are still there, except the gote is not at the knee, it is mid-calf.
as far as i know, a sharara and a lehenga are the same thing- i.e both are skirts, either a-line or fitted. there is no split in the legs like in the gharara.
