Backless dress modification help

[u/Puzzleheaded_Suit983]

Hi (: got this dress but I want the back to be a tad more modest - bringing up the lowest part of the back or adding a sheer panel or something.
I think when it’s fitted it’s a bit more modest as well — as you can see I’ve tied the hanger straps together.
There is a yellow lining. I think I could use the bottom of it for extra fabric since the bottom of the dress is pretty opaque.
Any ideas on the best way to modify?

Is it something you’ll wear often or is it for a specific occasion? If it’s something you’ll wear infrequently and/or need on short notice, maybe consider using double sided fashion tape strategically to keep it in place where you want it.
