Adding a nude mesh panel

[ModerationInEverything]

Hi, DD has decided that her prom dress is a bit too revealing (I agree) and I wondered if the simplest fix is to add a panel of mesh, like they have in dancing costumes. I don't actually know what I'm looking for though and would welcome any advice. The dress has the deepest v ever.
I have some sewing skills and am reasonably confident I could hand sew it in well.
I suppose a picture would be helpful, I'll set off I can find one!

It is similar to this.

I think it's pretty tricky to sew a panel i n and get the tension right. How about a bra with mesh like this https://uk.triumph.com/bras/padded/triumph-shape-smart/10214816.html?color=6719_Dark%20caramel

Thank you @hexsnidgett for the idea. I've never seen a bra like that before. Hmmmm

You can also get modesty panels online that clip to the bra strap. Not sure if they will work with the dress...

Tit tape?

Bandeau tops/bandeau bras? Amazon do Lacey ones that may work.

Or get the material and use the tit tape to secure it (disclaimer - I have huge boobs and have never used tape so no idea if this works .

Mesh for dancers -

Thanks @princesssugarless . Yes initially she was just going for tape but I wanted her to have options in case it doesn't work. The eBay link is exactly the sort of thing I was thinking.
