I joined the local pool (in winter) and so the maternity swimwear available was quite limited! Out of all of the options at Ripe I found these to be the most flattering and liked that they have adjustable straps and the knot at the front that can also be done looser or tighter (great for holding the girls in while doing aqua aerobics!)
I would usually go a size M/10-12 but the small in this fitted me best.
However, I have only been going to the pool twice a week for 5 weeks and the colour has faded significantly (even though I religiously rinse under fresh water as soon as I'm out of the pool). I have been wearing a swimming skirt (purchased elsewhere) which has not faded at all, so I'm confident that it is the quality of the fabric/dye and not too much chlorine spoiling them.
I'm quite disappointed for the price.
