    Lovely bikini top but as other reviews mention it comes up SO small, I’ve sized up considerably

    Ridiculous sizing by M&S! Sort it out.

    Terrible, inaccurate sizing! What a shame! A gorgeous rich peat-brown coloured bikini and classy looking design- love the beaded detail. However, the sizing is utterly ridiculous for adult women! Sort it out, M&S! Shame on the brand for making adult women feel like they are shopping in a teenage fashion store with this type of child-sized bikini! I am a UK size 10 (European 38) and wear 30/32D bra size, so not busty at all, in fact far from it. I usually wear M&S Small in tops. I ordered a UK M&S size 12 bikini, having read reviews that suggested sizing was way off. Nevertheless, this bikini top is so tiny and uses such little fabric (are they trying to save money by using less material?), that it barely covers the nipple area! I actually thought I’d ordered a child-sized AGE 12 bikini by mistake! I’d swap it for larger (size 14 might be less indecent) but resent needing to go up by two dress sizes due to M&S’s inaccurate sizing. Zero support, obviously, as it’s an unwired bikini but I expected that. Would look great on a slim teenager, or a very flat-chested adult woman, but anyone bigger than a size 8 or a perky B cup should shop elsewhere for swimwear, frankly.

    Bikini top is very small in the brown. I have black & blue in same style in my size. I had to increase by two sizes.

    Lovely bikini but size up at least one size! I am a size 14. The 14 was far too small and they were out of stock for 16. As I loved it so much I ordered the 18. Fits perfectly. Which is madness. So don’t be discouraged if they don’t have your size!

    Sizing is incorrect

    Bought 2 bikinis for my daughter: size 8 bottoms and size 10 tops. I exchanged this top for a larger size (size 14), as per the reviews, but had to get a size 16 and it was still smaller than the other size 10.

    Sizing is tiny!

    Good quality bikini, with nice bead detail, but the size is way, way out! I’m a size 6, but the top didn’t even cover my nipple. I reordered an 8 and then a 10, but neither were big enough. In the end I settled on a size 14! My advice is to order 4 sizes up.

    Very small sizing

    This is a nice bikini, quality is good and lovely style. But it is SO small, I am normally a size 8-10 in marks and Spencer’s clothes and wear a 32D. I had to get a size 16 in this to have a fit I was comfortable in. Bottoms fit fine (size 8 for me) and tankini also comes up small, I had a size 12. Fix the sizing please!

    Absolutely tiny!

    I actually double checked that this wasn’t an age 10 instead of a ladies size 10. It’s tiny, so was the 12. Ended up having to get the 16!! which is good, it’s a lovely bikini but size up twice, maybe three sizes. The bottoms are normal sized.
