Re: Sarees
sari made from any fabric can be stitched into a pre-pleated style for ease-of-use. (i.e. banarasi, chiffon, georgette, silk, tessa silk, satin, etc, etc, etc.)
petticoats are generally A-line skirts with a drawstring waist that allows you to adjust the tightness to your body/liking/comfort.
it was becoming popular to wear leggings (i.e. sort of a chooridaar pajama) under the sari to reduce the fabric and therefore give you a more sleek finish....this was bollywood fashion. Unfortunately this technique only works with saris that are not of a sheer fabric and the leggings remain hidden otherwise the look is spoiled.
to remedy a really sheer sari, it is recommended that you find a matching colour in satin and have the petticoat sewn. Make sure that the custom-stitched petticoat has no joint-seams in it. By putting the shine of the satin beheath the white sheer of the sari, you get a more elegant and polished look.
go forth and successfully wear saris........
