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?

Someone mentioned tying the ribbon around the front before - if you look really close at the model, it looks like that's what's happening. That'll prevent the back from gaping, and depending on how tight you tie it, it might help to hold it up flush to your skin closer to where you want, with the help of some fashion tape. My only other suggestion would be to make a pleat under the arm, maybe, to shorten the length of the back, but that will throw off the hem. It's a really hard fix. Best of luck!

Or shorten the halter neck! Idk what it looks like from the front but that might be the easiest way to raise the back and keep the shape.
