Swimsuits for 85 yo?

[Rollingdownland]

My mum wants me to buy her a swimsuit for her forthcoming holiday to Spain and I'm stuck. She's 85, tall and very skinny, so wants something comfortable but slightly covered up.

I've looked at M&S and Boden and can't find what I'm looking for.

Does anyone have any good ideas?

Bon Marche has styles that cover up fairly well. The only issue might be sizing, as they are quite generous. Sainsbury's Tu can be okay. Landsend are worth looking at.

this Marks one offers good coverage and is quite a thick material so is quite supportive. I know you aren’t looking for a post surgery swimsuit but it just means they are pockets for a prosthesis.

They have other zip front ones but this one is thicker and has a higher neckline. Otherwise maybe try triumph swimwear.

Zoggs swimwear isn't necessarily the most attractive but it works very well and you can choose from a range of features such as coverage, support etc. You would certainly be able to get comfortable plus reasonably covered up. https://www.zoggs.com/en_GB/swimwear/womens
Lands End is a bit more colourful and also comes in a Long fitting. They also have different options for coverage. ://www.landsend.co.uk/Women/Swimwear/ix-11307?cm_mmc=Google_Search_branded_20946515405ckwd-1734358949&s_kwcid=AL%216148%213%21687767736708%21p%21%21g%21%21kwd-1734358949&gad_source=1&_cclid=GoogleCjwKCAjwvvmzBhA2EiwAtHVrbzLkH4sUuZF76EC8UsAJ4_BCMqAYbu164ihUebk5dnb3cG5rtq0DZhoCT8sQAvD_BwE&gclid=CjwKCAjwvvmzBhA2EiwAtHVrbzLkH4sUuZF76EC8UsAJ4_BCMqAYbu164ihUebk5dnb3cG5rtq0DZhoCT8sQAvD_BwE

I find Zoggs quite short in the body.
The Land's End Tugless range come in a variety of length and cup fittings.

Thank you all so much. I looked at all of these and made her a shortlist, out of which she picked a couple I was going to order. But today I surprisingly found myself in John Lewis, and found a nice, soft looking navy blue one from Seafolly, which I've bought for her.

If she doesn't like it, I'll revert to plan A, so thank you all so much.
