I was in my hometown, Shillong, in July, and I bought these traditional pieces last minute - meaning: the day before leaving. So, they're not even completely stitched yet - the hemlines need to be embroidered and scalloped and whatnot (see on the yellow floral one in the pics below).
Our traditional attire (what sarees are to some of you), is called 'Jainsem'.
'Jain' means cloth, 'sem' means drape. Both words are Khasi language.
How We Wear It: There's 2 pieces of square fabric, which you drape over each other; each going from under the arms and pinned at the opposite shoulders. Gosh, I hope I explained that alright.
Please google it, if I confused you.
Pins for securing each piece of the Jainsems.
