I think you'll have to steal it from her dressing room. That thing looks like it was molded directly onto her body.

Like I said, specially designed for a personal friend or client by an up and coming (yet) unknown designer/seamstress. Keep track of her and you may be able to finance her career. I don't think it is a tango dress, think middle eastern belly dancer.

There is a dress on aliexpress
Same colour but not exact same
But it is vest match
(although u have shown a movue dress that would be a custom made so it is impossible to get)
Link for the dress https://www.aliexpress.com/i/32687530228.html

Its expensive
But i thinkn you'll like it

Non so dove puoi trovare quel vestito ma sicuro qualche sarta te lo cuce quasi identico

You can get a tango dress when you shop on amazon

Palazzo + corset should do the trick...

The episode where that was worn was the finals of season 18, DWTS May 19, 2014.

Here is a video of that dance.

The Designer listed on IMDB is Daniella Gschwendtner.

However Steven Norman Lee was with DWTS for 25 "seasons" (3rd season through the current 28th.), so he very well may have designed this particular piece.

Unfortunately I can't find anything definitive either way, and more unfortunate, I can't find a website where either of them sell their pieces.

The woman wearing the outfit is Meryl Davis. Maybe ask her if she still has it? >.<
Here's her Instagram | https://www.instagram.com/meryledavis/?hl=en

Also, the bottom section is pant/skirt, you can see something similar here on Randall Christensen's website, he was the designer from season 2-12 for DWTS.

Here are some stills that give you a better idea of the way the piece looks.

That's something you will have to hire a professional to make.

I think you should go with XP 10YT. I think her research is the most awesome headhunting yet imaginable. Finding a person like that is the beginning of a fantastic marketing and retail team for the fashion industry. Go for it, Miss Alikh!!!

See if this one works. The closest I could find:

Go to jumia and search for it

Go to jumia and search for it

You can find alot of outfits similar to this on this website https://www.fashionnova.com/ nothing on here is really too overpriced. I typed in "red lace teddy" in the search box on the website and saw several things similar to this. You would probably just have to buy a red skirt to go over top of the red lace teddy but there were some very cute ones that I saw. Check it out! Here is one I found that I liked and looked similar to the picture you posted https://www.fashionnova.com/products/sweet-to-you-lace-garter-teddy-red
