Tankini/shorts swimwear

[Missedmytoe]

Please help me find something! I'm going on holiday in July and the destination has a hot tub. I don't swim so don't have any swimwear but obviously will need something to be wearing for this.
I'm short and pretty round in the middle with not very good legs. Years ago I had a tankini type thing with a long, tummy-covering top and shorts type bikini bottoms that covered part of my thighs.
Is there anywhere among high street type shops that I can find something. I don't mind separates, I don't mind a swimming costume.
Must cover stomach and all of my vast backside.
Thanks

some are on sale @Missedmytoe

I recently bought one on vinted by the brand Shekini. It has a long flowy mid section and shorts rather than briefs which I much prefer. Like this!

Thanks for all the suggestions. I did try on a few swimwear pieces whilst out at the shops yesterday and I feel worse about having my stomach on show than my legs.
I suppose I had forgotten about one-piece swimsuits.
The skirted ones might be a good option, as they hide more.

Look at Yours. they are fairly cheap and cheerful and very pretty.

Have a look at Next online. They have quite a few options for lots of brands, not just their own brand. I bought a Joe Browns tankini from there last night.

Just beware, the dress type ones can float up in the water unless you tuck them in to the leg of the pants or you put a stitch in.

I came on to say Next too. But watch out for their random sizing... I ordered swim shorts and swim leggings (so essentially the same thing in different lengths) and one fitted and the other was so big it fell down...

Tu @ Sainsbury has some great swimwear at the moment, swimsuits etc not too pricey I would have a look there!
