speedo maternity swimsuit black

Sizes: UK XS, S, M, XL and XXL (18). Choose your pre-pregnancy size.

Why we love it: It’s plain, functional and well made, so fab for regular swimmers, as are most Speedo swimsuits. 

It comes highly recommend, too, by scores of pregnant women. “Love how this has fit me throughout my stages of pregnancy AND that I’m pregnant with twins!” said one. 

There are a few niggly bits to say about it here and there (especially if you’ve got a *really* large chest), but definitely one of the good’uns. 

Available from: Speedo

Available from: H&M

7. Seraphine Black Sweetheart Maternity Tankini, £42

Sizes: UK XS, S, M, L and XL

Why we love it: It’s a 2-piece that you can pull down over your hips or wear higher so your bump’s on full display. The bottoms sit under bump – and generally it has lovely, soft cups and a crossover back for a little bit of added style.

Available from: Seraphine

8. Wolf & Whistle Maternity Wrap Swimsuit, £31

wolf and whistle red

Sizes: This one’s available by cup size, generally for bigger cup sizes. Keep in mind that if your boobs have grown or swollen in pregnancy, you may need to find out your new size.

  • 30, 32, 34 and 36 DD
  • 30, 32, 34 and 36 E
  • 30, 32, 34 and 36 F

Why we love it: We like that its designed for a bigger bust – which many of us experience during pregnancy (if not before!).

There’s also lots of room for your growing bump to stretch out. However, we’re not sure what this sizing means if you’re bigger on bottom than top…

Available from: ASOS

9. JoJo Maman Bebe Black Ruffle Maternity Swimsuit, £29

jojo maman bebe swimsuit

Sizes: UK S, M and L. JMB says to choose your pre-pregnancy size.

Why we love it: The removable straps are brilliant – there are a fair few reasons we can think of why straps might annoy you while expecting. Especially if you’re just chilling by the pool and not actually swimming…

Available from: JoJo Maman Bebe

10. Mamalicious Flower Printed Swimsuit, £35

mamalicious swimsuit

Sizes: UK XS, S and L

Why we love it: It’s a light print, hard to come by (when it’s not stripes) – but also it has adjustable straps that can be turned into a halter neck, and a nice v-neck neckline.

There’s also some string under the padded, comfy bust so you can adjust a little bit as your boobs change size.

Available from:  Mamalicious

11. Seraphine Adjustable Nautical Stripe Maternity Bikini, £42

seraphine bikini

Size: UK XS, S, M L and XL. Seraphine says to choose your pre-pregnancy size.

Why we love it: There aren’t a great deal of maternity bikinis out there, so we like that this one has a waistband on the bottom that can be pulled up to help you support your growing tum. The straps can also be left out.

Available in bright blue, navy polka dot (both on sale for £25) and striped.

Available from: Seraphine

12. Splendid Cross Back Maternity One Piece Swimsuit, £108.18

Why we love it: The dresskini is perfect if you don’t want your bump too on display, but still want to stay cool by the pool. There’s a V-insert to cover your cleavage if you so wish, a soft cup bra, and 0.75 inch straps which can be worn straight or criss cross.

You will need to buy some bikini bottoms to go with it, though!

Available from: Mermaid Maternity

14. Emma Jane Maternity Swim Cross Back Swimsuit, £24

swimsuit

Size: UK 10 and 12

Why we love it: It’s fully-lined and ruched at the sides so your bump has room to grow, the bra bit’s elasticated (woohoo) and it’s pad-free, wire-free. Keepin’ it simple – in a nice, eye-catching colour.

Available from: Matalan
