This is a beautiful white, satin, strapless, ball gown with beaded appliqués, and corset back (aka a slightly forgiving fit at the top).
The skirt is organza, with a chapel length train. It does not have pickups, however it is pulled up at various levels on the side to give it a layered appearance.
The dress is very well constructed and does not require any additional petticoats or even a bra for that matter.
