I need maternity swimwear however usually I swim in a legsuit and I can't find a maternity legsuit anywhere! Would non-maternity swim shorts worn under my bump with a maternity tankini top work do you think? I wear standard underwear throughout pregnancy and I guess the waistband of the shorts will be a bit stretchy so I'm thinking this might be the only solution? Why does nowhere make maternity legsuits 
any recommendations for swim shorts that might work well for this purpose?
