MaggiRos,
Hi, here are a few numbersof patterns you could use as a base.Simplicity 4055,
Butterick 6630 and 4890.
The net and lace over gown/top looks like a triangle shawl shape with the front
ends cut off level with the high waist, from what I see. I did not watch the
show so I don't know
Here's one from Past Patterns.

These types of gowns usually have an unssen lightly boned foundation bodice
that the other stuff is draped onto. A pattern like this might include such a
detail.
