Nice tankini top

Originally posted on marksandspencer.com (UK)

This is a nice simple tankini top. I like the square neckline. I am a 12, and normally wear a 34D bra. Due to other reviews I bought a 14, and that fits perfectly. It could be a bit longer, but I am long waisted, so probably fine for most people.

Flattering and Comfortable

Gives you a nice shape and stays in place while swimming. Flattering and long enough around the stomach and decent cup size.

This tankini top is a great shape, true to size and very comfortable. If it came in different colours I’d buy one of each.

I had to size up in this. The shaping is good but very tight. I. The correct size it is a lovely item. I don't like tight clothing. Could be worn as a top with trousers. Support is good. Recommend.

I’m a size 14 in most things but 14 was a bit tight so went for the 16 and it’s more comfortable.

Square neck Tankini top

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This is a flattering shape and nice tankini top however, I had to go up a size for a comfortable fit. I normally wear a 14 top in clothes, occasionally a 16 so that’s what I initially ordered but I found this just too tight and uncomfortable to wear so exchanged for an 18 which is better. I thought the price point a bit higher than I expected

Really good fit especially as my tummy is a little larger than I’d like. It gives a more slender shape which is great.

Soft cups

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Feel to old to wear bikini now, but tankini is like aswimming costume cover when standing, bikini when laying down. Bought this one because of the soft cups, and a bit more cover to the boob area. I read reviews and i had to go up a size. Its fine, but would prefer a bit more tummy control.
