Very flattering but a bit more needed in the bum

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Usually a m&s 14L. Bought 18 long. Very flattering and supportive in the right places. A shame most swim suits are high leg and don't fully cover a larger bum.

Quality great and can buy in longer length

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I only buy the costumes that come in the longer length so there’s not much choice to begin with. This one I’ve had before, it’s ok but I’m finding the backside covering seems to be more skimpy than when I’ve had these before? It could be me I guess but have now found this with two costumes from M&S. Would buy again as need the longer length and so little to choose from.

I like this, it's flattering and comfortable. I do think things have got smaller (I know I haven't got bigger!) as I previously got the 10 (my normal size) but it was too small.

Its ok, but too snug in size.

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Bought this for my regular swimming sessions and I really liked the square neckline rather the usual plunge style. I am a size 14 but always find I have to size up on swimsuits, however I had to go up to an 18 with this suit and I still found it quite short in the body, even though I'm only 5"4 and it feels even more snug after thr first wash. So im sorry, but I wouldn't recommend.

Good quality but size getting smaller ?

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

It seems that the sizes are getting smaller and I deliberately bought ‘long’ and the strap is on the very end . Size 14 was always good and I am sure my body hasn’t changed !!

Supportive swimsuit that’s also stylish

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Elegant and stylish suit that also supports in the right places. Would be nice if the straps were a bit wider like the Boden version but can’t really complain given the price. More colours please.

Lovely but narrow bum cut

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Had a similar swimsuit from M&S which must have been 10 years old and wanted another the same after the elastic started going. Just as good, nice and flattering and nice neckline however the bottom coverage appears to have been cut a bit narrower so feel like I have to constantly be pulling it so it doesn’t ride up rather than just having a normal full coverage. So docked a star for that

Great flattering cut, but the sizing is off

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

The cut on this costume is really flattering. There is just the typical sizing issues. I am a size 12 and 5ft 5inches. After a previous experience I ordered the long version and it does fit in the length despite being for taller people. It’s also really snug so not a true size 12. I’ll reorder a 14L. Also the tummy control is non existent. I might even say it highlights the area?

Long body swimsuit which looks good on . I’m of an age where everything needs to be held in and this fits the bill. Would have liked more choice of colours.
