Anything I can do for a top that;s a bit too low cut ?

[70isaLimitNotaTarget]

I'm not looking a sewing (as I'm rubbiish) but it;s a sequin top that has a V neck and it's a bit low cut for my comfort .

Is there anything like a fancy lace underlay I could put on?
I don't want to wear a massive necklace and I think a scarf would just make me self concious .
It's gold colour .

If all fails I'll try it back-to-front !

(It was an eBay bargain )

TIA

Yes, have a look on Amazon. I got some pretty inserts that attach to your bra and cover too much showing. They were not expensive.

I have a huge scar which I’m very self conscious about and found some cleavage covers on Etsy that are fab. You can get them in a lot of different fabrics and colours.

As @BellaAndDave said etsy have some https://www.etsy.com/uk/search?q=modesty%20panel&ref=search_bar

I bought some modesty panels from Amazon to wear under a wrap top that gapes a bit. Something like that may be useful. They clip to your bra straps and look like you're wearing a pretty cami underneath.
There a lots on Amazon and come in loads of colours

Being small of boob I have this a lot and I don't like the look of a cami underneath.

I have a stitch gun like this
MicroStitch Avery Tool, Multi, 18x3x22 cm : Amazon.co.uk: Home & Kitchen

So I just pop one or two in to hold it together
