The square neckline and adjustable straps allow you to customise your fit, while the high UPF50+ protection offers peace of mind in the sun. Added stretch ensures all-day comfort whether you're swimming in this swimwear top or relaxing poolside.

Returned very small for size

No, I don't recommend this

Disappointed. Bought a 16, as I hate tanking tops that are too tight but this ones was so tight I could barely take it off again. Returned!

Size up and it’s lovely

Yes, I recommend this

Size up and it’s lovely - I bought the zebra print one in cream and black and it’s very comfy, doesn’t ride up, and you can remove the pads. Looks good with plain black bikini bottoms.

Square neck tankini

Yes, I recommend this

I prefer a tankini rather than a full costume, this one is bright and colourful. Usual size is normally 6/8 but I sized up to a size 12 which made it easier to get on and off. Haven’t worn it yet, so can’t comment on the wear or how it washes. I have noted comments that the inner ups in the top go a little askew when washed, hence M&S should have put the usual slits in the inside material so the padded cups could be rearranged as necessary or even removed if desired.

Flattering, good fit and good value.

Yes, I recommend this

Bought it for a holiday. Great overall look. Flattering shape. Normally spend a lot more money on swimwear for a good fit but I was quite impressed by this one and great value for money.

Lovely but!!

No, I don't recommend this

I love this tankini too, but best for posing not good for swimming. The fabric is so thick that it takes hours to dry, even left to dry overnight it is still slightly damp in the morning. We are somewhere above 30degrees too.
