Pregnant - bikini or all in one?

[LoveInAColdClimate]

I'm going to start swimming to try and stay fit while pregnant (am 12+5, but already have a bump- the rest of me is still slim (size 8) though). I can't find a maternity swimsuit I like - will a bikini look tacky? I have a sports style bikini that stills fits and will stay on firmly. Alternatively, has anyone got any recommendations for nice maternity swimwear? Thanks.

Personally the sight of my naked veiny bump was so minging I wanted to cover it up so went with a costume, but the only one I could find was super frumpy from Mothercare. Wore it anyway as I was past caring what anyone thought by then! Can you still get nice tankinis? But I think if you've got a nice looking bump then go for the bikini, why not? I don't think it's tacky.

I hate bathing costumes personally so bikini
