      M&S says

      Whether you’re swimming laps or bathing by the pool, our plunge swimsuit is designed for both comfort and style. Using clever Secret Slimming™ technology, an inner layer of control fabric holds you in all the right places for a flattering shape. This black swimsuit has moulded cups and a plunging neckline to ensure a truly feminine look. Tummy Control will help you look your best and Chlorine Resist prevents pool water from ruining the colour or fit of your swimwear. The adjustable straps allow you to find the perfect fit, so all you need to worry about is which sunglasses to pair it with.

      Secret Slimming™ Plunge Swimsuit is rated 4.3 out of 5 by 70.
      Rated 5 out of 5 by from Perfect I don’t normally write any reviews but I was so impressed I thought I need to. Was a last minute purchase before my holiday, so wasn’t really expecting to get it right first time round. This swimsuit is just perfect, I’m size 12 and usually buy all clothes from M&S this size without even trying them on in store, as it’s true to it’s size. But with swimming suit I thought I need to try it on properly. I choose to go size up and I’m glad I did. It fits perfect, it’s not too tight around my tummy but holds it nicely nevertheless. Fabric is just a lovely quality, and adjustable straps as well. I have a waist in a swimsuit! Really happy and can’t wait to wear it on my holiday! Never disappointed with M&S , thank you!

      Rated 5 out of 5 by from Flattering sunbathing suit The 16 is a good fit for my size 14/16, cup 34F frame, the liner layer helping to camoflage my lingering mum tum rolls... though unfortunately the trade off is that it does make for a warmer than usual feeling on a sunny beach. Quite low cut as per the title, but still supportive enough to not feel like I’ll fall out, but am not willing to try active pursuits- eg Perfect for lounging, spa days, gentle swimming but not aquarobics! This looks expensive on- in fact extremely similar in fit and look to a branded £90 suit I also simultaneously ordered from elsewhere so kept this one instead and I could replace several times if the chlorine doesn’t treat it kindly longer term.

      Rated 2 out of 5 by from Cups not flexible The quality and the design - on the face of it - should make me look great.but, as a slim, small breasted person the cups are just to rigid and because they don't really flex with movements I am afraid of showing rather too much when i'm at aqua classes, so this suit has gone back. I would like softly padded cups, a bit like M&S's T Shirt bras, which provide some shape without too much structure. I guess this is the challenge for M&S trying to make a design to fit all sizes. For a fuller bust this suit would probably be very glamorous.

      Rated 5 out of 5 by from Great style and value So pleased I bought this. Reviews were useful regarding size as I am a 12 in trousers etc but went up a size for comfort and best fit. Realised that friends do this for swimsuits to avoid bulging out of usual snug swimsuit design. Fit with upsize is perfect. I swim regularly and used it day after purchase and it was great. I'm average breast size 36C -ish and top fit is fine, no feeling of falling out. Others have noted it reveals too much but not for me - top style is flattering. Feel like I can wear with confidence at beach, pool and swimming. My last suit was an expensive Lands End one - did last but this M&S one seemscjust as good at more than half the price (and slimming around waist). Advice for all (at least us in middle age group - is go up a size).

      Rated 5 out of 5 by from Can't rate it enough! I hardly ever write reviews but this swimsuit is just outstanding. I'm 5ft7, overweight by a fair few st with E cup breasts, I've chosen the 14 long length and it fits perfectly. It clinches in all the right places, flaunts your best parts and hides your worst. I've got a long way to go but I already feel slim and confident in this. If you have quite small breasts it probably wouldn't fit as well however as the cups are quite generous. I can't wait to take my baby swimming now whereas before I was dreading it! Thankyou M&S

      Rated 5 out of 5 by from Good quality The quality and style of this swimsuit is excellent, I only returned it because I am in between sizes. This was a little too big and as I am hoping to lose more weight prior to my holiday next year (fingers crossed) I will wait and buy this hopefully in a smaller size before I go on hols..

      Rated 4 out of 5 by from The typical mistake This is a lovely garment, very well finished and well fitting... except for the cups. I've already given up finding a swimsuit without inserts, and this is the usual problem I find with them that I forgot to consider when ordering, but wasn't offered any type of information about it in the online catalogue. I am a plus size. My breasts are NOT a plus size. Apparently, all manufacturers agree that if you're bigger than a size 14 your chest arrives to places right before the rest of your body does. With this in mind, now I do not know whether to just ignore the problem or add some ballast to fill the large spaces. I only hope it doesn't become a bigger problem when trying to swim, because (oh dear!) yes, I do wear swimsuits when I want to swim. I am not a sunbather. Sure, I could have gone to the shop and tried it. It's only that they don't have swimsuits at this time of the year in the stores. And I've never seen one of my current size at any time of the year in the stores. Aside from this, this is a great item.

      Rated 5 out of 5 by from It does the job Always have trouble finding long enough swimsuits but this does the job and is good value in comparison to other suppliers. I really wish that there was more choice regarding colour and pattern.
