The first one uses chiffon at the front and velvet for the sleeves maybe ...and the trousers are of jamawar ..there's velvet and banarsi pati on the border of frock ... not sure how much of fabric is needed for it though :D
Any idea about how much of the fabric is needed for the 3rd picture i.e. Katrina's black dress H&NK,The first one worn by Lara appears to be Malai jorjet shirt, chiffon sleeves & duppata. The total fabric for shirt would be around 4.5 yards.The 2nd picture probably has kataan silk shirt. For this one, even 4 yards would be enough.
Lara's dress: Korean chiffon (with lining) not sure though
Material need for this type of style , 6 mitres, for all above dresses for a good ghair,6 mtr is enough and
for normal ghair 3.5 mtrs
trousers : 2.5 mitres
