    May suit some people but not me!

    No, I don't recommend this

    This must be the worst swimming costume that I have ever tried from M&S. The bust was around my waist and would not pull up. I have returned it.

    Great fit, great quality.

    Yes, I recommend this

    Great costume for daily pool swim. The quality is obvious and so far no sign of colour fade from the chlorine.

    Disappointed.

    No, I don't recommend this

    Do not wear this item to sunbathe in. The sunburns through the material. You'll need to cover your tummy with a towel just to be on the safe side.

    Great quality/fit

    Yes, I recommend this

    Started Aqua fit, and have searched numerous shops/online stores for a decent plus size costume. Which is also affordable as the prices for costumes is extremely high. I found this one when I was having another look. The back makes it easier to get on and off. It supports large boobs and its a nice over all fit. So much so I bought a 2nd one in the sale.

    Lovely practical costume

    Yes, I recommend this

    Ideal for lane swimming. I’m ordered 2 Speedo costumes from M&S for choice. Having a full bust I felt more confident in the other as need it for holiday swimming with grandkids too. However this costume is well made with plenty of body length too. Speedo sizing can vary so I think it’s best to also order size up to compare. Although M&S did get it spot on.

    Fabulous fit swimsuit for larger bust

    Yes, I recommend this

    This is the best swimsuit I've found in years. Since M&S stopped doing the longer length & 26 I've struggled to find a cossie that fits. Everything about this speedo costume fits really well. So many costumes these days have far too large leg holes, these are almost perfect. Sits at a perfectly flattering not too high not too low leg position and does not shift about at all. Excellent space for larger bust (I'm 40G) Good body length, could be a tiny bit longer still, as bust section sits lower than would be most flattering for me. As others have said straps could go a little shorter still for this reason. Great back coverage. Mostly I love this costume as it just stays put whilst I do laps. No re-adjusting needed. I hope the xtra life elastane is chlorine resistant as I hope to wear this costume loads. I have already bought another. I'd say it is fairly true to size, my actual size is really comfy, the size down would hold my tummy in more and still has room for G cup size, but the elastic may not last as long! I've kept one of each. I'd love it in some dark patterned colours as they can be even more flattering than plain black.

    It’s a good swimsuit but the straps could be shorter for a better fit around the bust.
