Low v-cut dress, how to not to flash

[RumpoleoftheBaileys]

I have a long dress with spaghetti straps and a low v. It ties at the back, so no bra possible.

In my head, I have a complicated plan involving tape. Before I cause injury to myself and/or another, does anyone have any recommendations?

Dress like this (but not quite as revealing).

FWIW, I have a small chest.

Have you tried it on and what does it look like without intervention?
I think if you have a small chest and it is a snug enough fit at the back it will look fine.

I have tried it on, will need something to hold it in place

I think this is the sort of thing tit tape was invented for

This looks like the stuff.

I realise I'm drip feeding here. Tried some of the double sided tape and was unconvinced. It was a generic one from years back though. I see the eylure one has great reviews though

Wig tape works wonders compared to the tit tape

The glue decomposes over time so you might need to buy newer stuff.
