Very cut away at the top of the legs

No, I don't recommend this

If I was 30 years younger then perhaps I could have worn this swimming costume, but it was very brief and cut away at the top of the legs. I therefore returned it. I loved the design and colour but was very disappointed.

Great tummy control and so feminine!

I’ve been looking for a swimsuit that makes my tummy look flatter and doesn’t make my bust look too small. I’ve tried lots of swimsuits from different brands, but I ended up buying this one because it was the best. I’m 170 cm tall and weigh 54 kg. I got a size S, and it fits perfectly!

It looks good and it isn't very thick, so good for hot days. It doesn't press the tummy too much, and it has a beautiful design.

Gorgeous colour and style

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Lovely colour and style of costume, the only critique would be it seems to be a little short in the body. The fit around the stomach is good and flattering, the bust support is sufficient that you’re not worried about exposure.

A great shape that fits well and is flattering both around the waist area and the bust.

Baggy around the top of legs and bum!

Originally posted on marksandspencer.com (UK)

Such a lovely style and red colour. It fitted everywhere except the tops of my legs and bum where there were big gaps all round. Probably just because of my body shape but a smaller size wouldn't have fitted elsewhere. Such a shame.

You will love this swimsuit!

Originally posted on marksandspencer.com (UK)

I am a size 10 but always size up in swimwear so I ordered a size 12. I wasn’t too sure if the deep plunge would suit me but as soon as I put it on, I loved it. The fit is perfect for me. It is very flattering. I would definitely recommend this swimsuit.

Much better than I was expecting, lovely brown colour that’s quite flattering, nice styling that’s very forgiving.

Extremely flattering

Originally posted on marksandspencer.com (UK)

As a mum of three my body has been through a lot and it’s really hard to find flattering swimwear that makes me feel good without it looking frumpy. I had lost hope after trying on LOTS of options then I found this…. It fits brilliantly! It is cut in all the right places and makes me feel really confident. Went a size up so it’s extra flattering. Would 100% recommend :)

This was the hero swimsuit out of the two I purchased for my family holiday. I bought this in brown and it was such a pleasant change from the usual black swimsuit. I’m quite self conscious but felt great in this. Thank you M&S for the detail at the back for a bit more support whilst keeping it flattering!

I bought swimsuit in fern green and it’s absolutely beautiful. I normally buy Boden swimsuits but decided to try M&S. The colour and fit are perfect.

Not enough bum coverage

Originally posted on marksandspencer.com (UK)

It's a nice colour red and I like the plunging neck line. The disappointing thing is that M&S love to cut corners these days and sell it to us as style. This swimsuit just needs a little more fabric on the bum. If you have any cheek flesh at all, it's all going to be on show. Just sayin!

Flattering swimsuit. Went for the long which has definitely helped me to not get a wedgie! Not that I have a particularly long torso. Still slightly rides up in the bum area but most swimsuits do!

Thought I'd better invest in a swim suit. This one is a good fit and the tummy control certainly helps. Love Khaki colour so all in all a good buy.

Sexy summer bathing suit in Red!! Deep plunge top for gentle swimming and lounging. Not for diving or endless hours of training in the water but I did not buy it for training.

Fabric is very thin creating a camel toe issue which means I couldn’t wear it on holiday
