Lovely

Yes, I recommend this

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

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.

Baggy around the top of legs and bum!

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!

Yes, I recommend this

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

Yes, I recommend this

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 :)

Beautiful colour and design

Yes, I recommend this

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!

Beautiful green swimsuit

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

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

Yes, I recommend this

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!

Great fit

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

Great swimsuit

Yes, I recommend this

Brilliant swimsuit for the (£36) price! Sizing is slightly small, I opted for usual size 12 in longer length as 14 too big around bust. Brown colour way is a more flattering option than black for fair skin.

Poor fit

No, I don't recommend this

I bought this for a more supportive and flattering fit. I’m a size 8-10 but with a slight belly pooch due and a bigger bust. Sadly this one-piece had limited compression around the stomach area and the cups were so small it looked ridiculous. Returned for a refund.
