Ruined my fave cossie HELP

[Canyoudigityesyoucan]

Help!

Going away this week and retrieved my old faithful white cossie from my wardrobe ready to pack. It had some yellow patch stains on stomach from what I think was sunscreen.

I decided to first treat the yellow stains with some Ace fabric whitener and wash, but it seems when I did this it soaked through the cossie and took the red dye from the care label and made the yellow spots red…. Sigh.

So I decided in a moment of madness last night to soak it in standard (white) toilet bleach with water overnight to try and rid it of all stains and make it whiter.

I’m an idiot because I’ve now woken up to a pale yellow swimming costume. I’ve washed in hopes it was temporary but it’s not…It looks like the colour of urine!

I love this cossie so much I wish I’d never tried to whiten it. It’s Figleaves and discontinued!

Anyone have any suggestions as to how
I can get it back to white or is it dead?

Sorry, really don't think there is any way to rescue this.

I'd take it with you and leave it out in the sun all week on the off-chance it might sort it for your next holiday. Then check vinted for a back up.

I think I saw someone advise someone to bleach with the expectation of it going yellow but then to put in on the line in the sunshine and it turns white.

I could have completely misremembered of course but it doesn't sound like it could get much worse?

Could you try dying it a darker colour- I’m not sure you’ll be able to get it back to white but you might be able to make it wearable it by dying it black/navy/charcoal/plum etc (just make sure you use the right type of dye for the fabric).

Soak it in vinegar and water. It might help to neutralise the bleach.

I don't think there's much you can do for bleach stains.
