Show off your blooming curves and soak up some of those essential vitamin Ds at the same time. The above swimsuit from Figleaves comes in at £60 but the sequins will ensure you're the most glam poolside mum to be.
The monochrome look is always sophisticated and this £25 tankini from Mamas and Papas has a flattering halter neck.
Yes the model looks about zero weeks pregnant but I can assure you this is a maternity bikini and the ruched sides will accommodate a growing bump. The two parts are sold separately and the top comes in at a bargain £4 from ASOS.
