Great swimsuit.

Yes, I recommend this

Good quality swimsuit, fits true to size. Used for exercise in local pool but would be equally as good on the beach.

Great swimsuit

No, I don't recommend this

Great quality and shapes well. It would be good to have adjustable straps. This was the main reason I returned, couldn't get it to fit right around chest, even trying 2 different sizes.

Not great!

No, I don't recommend this

It’s attractive and glad my breast size isn’t too big as feel I could fall out at any moment! Tummy control is poor and this costume only feels good with high leg tummy control pants underneath! Because it was reduced in price I’m OK with it but wouldn’t buy another at any price!

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!

No, I don't recommend this

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.

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.
