After trying multiple swimsuit for my growing belly, I finally stumbled this one. Pre-pregnacy I was size 10, but I opted size 14 just to be sure. Its a bit big on my shoulders but fits perfectly on my tummy. I absolute love it

Brought this in my usual size (size 10) for a spa day at 26 weeks pregnant. Love the square neck line and side strings.

This was bought for my granddaughter who is 36 weeks pregnant. The fit was wonderful having tried so many costumes from different retailers she was truly ecstatic at how wonderful it fitted her.

Great swimsuit that can grow with you!

Bought in first trimester as my regular costume had died. It's perfect and I hope will grow with my bump! I think it will also be great post pregnancy and doesn't look frumpy. Sides are adjustable too which is fab and square neckline gives it a bit of something extra.

Full disclosure - I am not pregnant but I carry most of my weight on my tummy and I have never really found a swimming costume that covers my tummy without riding up, but this is the one! It is long enough in the body and the drawstrings mean you can literally shape it around your tummy to feel covered and confident!

Excellent value, great fit ❤️

This swimming costume is such a fab fit. Excellent support for both the bump and the boobs. Bought 2 sizes to try on but nothing between them really so went for the larger size. Lovely bright red.

I bought a size 10 to wear whilst 32 weeks pregnant, it was a great fit, stretched around my bump perfectly and felt so comfortable - very happy!

I could not get the correct fit on a swimsuit due to a bloated belly, so I thought why not go down a size and get a maternity costume, which may I say is a fantastic trend setting design and it fitted amazingly so my problem is solved and I feel great as in a smaller size, win win
