No breast coverage

Awful swimsuit. I tried it on and liked the appearance and tummy support so kept it, however when I wore it in the pool, it became apparent that there was absolutely no support or coverage on top and my boobs kept coming out of the swimsuit (rather embarrassing and constantly had to keep readjusting myself). Sadly I cannot return because it’s been worn. I would not recommend.

This swimsuit has clearly never product tested!

This item has clearly never product tested in water or on a human. There are thin pads in the cups which are sealed in. If you get into water and then take the costume off, the cups flip over themselves and you have to try and detangle both of them through the fabric. Which is near impossible and takes an age, just to do it again. Same when you wash it, same when you simply get in and out of the water too. It’s such a shame because the green colour is gorgeous and the shape is really flattering but this suit really is faulty & has been a waste of money.

Yes, I recommend this

It’s a lovely colour, great quality and a perfect fit. I ordered a long as I am just under 6ft tall, and I usually find it hard to fit swimming costumes that my body well!

No thought has gone into this

No, I don't recommend this

oh dear oh dear oh dear. Tummy controlling it may be: bosom controlling it is not. M&S: why do you sell swimsuits like this in sizes that make women with large bosoms THINK it will fit, only to be disappointed? Please read this: simply making something bigger doesn't mean it actually FITS!!! Literally bent over to pick up my phone and one boob fell out. Photo attached.

Great cut and great colour

Yes, I recommend this

Gorgeous swimsuit - one of the best, most flattering shapes I’ve ever bought. It’s a low neckline but my double Ds coped fine! Only criticism is the placing of the cup pads - the straps are long and the pads sit too high. I ordered the long version first and the cup pads sat up near my collarbone!

Not for me

Yes, I recommend this

Two beach holidays this summer so I bough this swimsuit for its rave reviews. Unfortunately the 12 ( my usual size) was too big on the top and too small on the bottom. The quality was great & it’s a fantastic price so if it had fit I would have definitely kept it.

Great flattering costume in longer length

Yes, I recommend this

This is the first time I’ve had a costume that fits my long torso perfectly! The tummy control is very subtle and smooths rather than sucking any parts of me in but that means it’s a comfier fit as a result. Really flattering and rather busty when on. Quality seems really good too for the price.

Amazing Swimsuit!

Yes, I recommend this

Fits like a glove, I sized up as I tend to do with swimwear - shows the good bits and disguises the not so good bits! Very comfortable with nothing digging in. Love it so much have bought in 3 colours!

Didn’t work for my post partum body

Yes, I recommend this

I’m 5 ft 2, size 10, big bust from breastfeeding , 5 months post partum and bought for the tummy control element but the suit didn’t do me any favours. The plunge neckline was just too revealing and small for my cup size.

Tummy control bather

Yes, I recommend this

Lovely bather , Fabric very soft and looks lovely on. I went up a size because I didn’t want it too small on the bust area. However the tummy control was lost as too big. I kept it as it will great in the hot tub. Will try a smaller size next time to see how that works.

Great swimsuit, super flattering

Yes, I recommend this

Really nice swimsuit. Great colour, good fit and really flattering. Only issue is this green colour seems to have been made less well than other colours - on the front top section the seams don’t sit properly and roll out so the stitching is visible on the outside and the removable padding doesn’t quite sit properly. I noticed this on two size 12 and a size 14 that I tried on so it seems a problem across all pieces. The black and brown colours I also looked at didn’t have this issue.

Stretches when wet..

No, I don't recommend this

Lovely flattering swimsuit, I actually bought this in a larger size as I’m 21 weeks pregnant. Only issue was I didn’t realise it would stretch when wet so it then became saggy for the majority of my holiday. Also by the end of the week I noticed that the fabric had bobbled under the arm pits. I guess you get what you pay for. Not bad for the price, but not amazing.

This swimsuit is so flattering and hides a few tummy bumps perfectly. I felt so good wearing it, so much so I’ve bought it in red, black and brown colours too. M&S you’ve nailed it with this one, thank you.
