Why the hell do my swimming costumes do this?

[Silverswirl]

I’m beyond frustrated. Can anyone relate / give advice?
I have large boobs so need a non padded, NON moulded cup, underwired swimming costume. (Would never wear bikini)
I get them from figleaves (now simply be I believe) and they look great, fit well, hold everything in place. They arnt cheap but I can’t really find anything as good. All swimming costumes seem to come with moulded cups which do not work with my boobs at all.
The problem is that every flipping costume really quickly goes see through at the bum after a short time. The water degrades it.
I always rinse well with cold water.
I seem to have to buy a new one every year and now with my latest one I’ve only worn it approx 10 times and it’s already completely see through at the bum.
I’m so cross as these costumes cost around £60.
Please tell me someone has an answer to this 😩

Oh dear, apologies for typos. Still getting used to typing in new phone

Sorry, that should read Buy Speedo

Vitamin C supposedly neutralises chlorine. I have taken to putting my suits through a 15 minute cold wash with mild detergent and half a soluble Vit C tablet after every use. Too early to say whether this is working as the current suits are only a month old (in the pool on average an hour a day, alternating suits).

Oh do bugger off would you

Sitting by the pool or easing in from sitting on the edge will definitely do this. Pool side is often rough to prevent slipping after all.

My black Speedo cozzies have lasted really well, with no visible wear at the bum area. I put them in the machine the minute I get home, with ordinary detergent. Or if I'm on holiday, I rinse them really well then soak them for a while in cold water.

Ah, zombie thread.

^THREAD BUMPING TROLL*

All my Australian swim friends wear Funkita because they're the only thing that survives high levels of chlorine and UV. Fashion swimsuits disintegrate almost immediately.

Funkita have high support bikinis and one pieces. I'm flat chested so can't comment on the support, but their normal costumes are great!

Is it possible (don’t hit me!) that they’re too small? I am the opposite way round- my bust is two dress sizes bigger than my bum- and my all in one costumes go see through up top rather than on the bottom.

I agree with this. My swimsuits last years. Also, don't hang on a heated towel rail!

I buy zoggs and speedo and have worn them up to 4 times a week for years, they last.

I’ve never had that happen. The bottoms are double layers, too. Mine are from
white stuff.

Need to wash after every wear. The chlorine degrades the lycra in the fabric. Or buy non-lycra containing suits.

Happens when they’re too small and the material is stretched

"the instructions actually say hand wash with cold water."

That doesn't mean simply rinse in cold water: you need something to coax the chlorine out. Soap can help get it out of the fabric. simply rinsing in plain water is not enough, needs a good exposure to some kind of soap or detergent.

I'm not that fussy which kind of detergent (or soap), but always soak my suits after a swim in soapy water. I swim 1-2x/week, my suits seem to last 100-150 wears.

I’m a 36E and have found this aa-sports.co.uk/products/zoggs-fine-romance-womens-tankini-set-black-2067190?variant=40585614393476&currency=GBP&utm_source=google&utm_medium=cpc&utm_campaign=google+shopping&gclid=EAIaIQobChMI4fO87dip-wIVzdPtCh2XCQaHEAQYByABEgL4q_D_BwE suit from Zoggs to be excellent for breast support. And as per @Hobbes8’s excellent suggestion, you could just replace with cheap black bottoms.

I get mine from boden. Never had that.

I'm big of boob and use Speedo. They've lasted years. Swim twice a week.
