Very flattering - order a size up

Gorgeous tankini top which is very flattering and gives a nice shape however, the sizing is so odd. I’m usually a size 8-10 (34C) and it was far too tight. The size 12 was tight but the size 14 was too big in the waist and padded cups. I went for a size 12 in the end. Not worn it on holiday as yet - hoping it isn’t too uncomfortable to wear all day in hot weather!

Good quality comfortable Tankini top. It fits true to size and is very flattering . The red colour is lovely. I just wish the bottoms were a better design .Unflattering and uncomfortable . So returned .

Decent tankini

This is the first piece of swimwear I have successfully bought from Marks and Spencer for a long time that I actually like. I bought a one piece last year but it’s serviceable rather than anything else. This tankini fits well. I bought a 16 top (36DD) and a 12 bottom. . I like red. The top is long enough for my body. However I would say overall the top is a small fitting. The bottoms are not in some places. Slight gap at one side. I felt altogether it is a bit expensive but that is what it is these days.

Really lovely colour great fit bought size 16 for 34g bust, usually HS 12 fit great on waist etc. Definitely recommend except the matching high waist briefs very strange did not cover properly showed the bottom of your bottom.

No, I don't recommend this

I used to buy all my swimwear from marks but last few years with the extra Lycra they are really tight and difficult to get on and off especially when wet.They do ride up at the back on small sizes as well .

poor quality and sizing too small

the sizing was wrong as I could not get into the size 8 as it was so small. Fabric felt cheap and flimsy.
