You can’t go wrong with a classic black swimsuit that slims your midsection! Lots of details here: generous underwire bra cups (C and up), fabric crossover on front and back midriff helps to conceal “overflow.” Lots of ruching on torso camouflages your midsection and backside. AND there is a little flutter piece hanging on the bum if you’re conscientious about that exposure! Very flattering… adjustable straps. This seems to run a little small, and it’s usually recommended to size up for a swimsuit, so this would probably best fit a 12.
