Great fit

This is such a flattering swimsuit. I’m over the moon with it. The longer length fit means I’m able to buy the size that actually fits my (longer) body without having to buy the bigger size. Gorgeous colour

Style for tall women

Yes, I recommend this

I have looked for one piece swimsuits at every price point, and singularly failed to find anything acceptable until I found this suit at M&S. For some reason most long swimsuits have a modest leg cut, which is not very flattering. So thank you M&S, for giving a tall women a bit of style. More, please!

OK for the gym.

No, I don't recommend this

This swimsuit is not really a tummy control swimsuit. There's not a lot of structure to it, but it's OK for the gym.

Not really ideal for larger bra sizes

Yes, I recommend this

37, Size 16, 36/38 DD/E, and I had the previous design hold in costume from m&s. I raved about that one. But I was a size smaller then. The old one lasted for like years and it is still looking good even though I swim a lot it just doesn't fit. This one looks amazing, like you will be admiring yourself in it. Especially the back!! I have back fat which concerned me but this was all I could find in a rush and it surprised me. It makes me back look good!! Tucks things away. And sure body positivity but they bother me. In this cossie they were INVISIBLE. Totally flat and pushed away I don't know whereabouts they hid it as it wasn't tight at all like the previous model. The plunge I was a little unsure of but I did look good in it. I just wish the cup sizes were larger. Bigger breasts need wider cups. I didn't feel secure. I could never actually swim properly in it. But it was great for my needs at the time, the spa and the spa pool and even though I felt like I'd pop out suddenly for a few hours at the start, it did remain intact for 5hours I wore it. The only slips were while getting changed and adjusting it to sit on me. I think being wet helped it stick to me better. The tummy was flattened, I've always had a huge belly and it did look slimmer but without any horrible constrictions at all. I was baffled how they did it. So yes, thoroughly recommend.
