Opt for a swimsuit with added support. Be it secret support panels that will pull you in or underwire to keep your boobs where they belong, spend the most you can afford. As in many areas in life, you get what you pay for and the material used in slightly more expensive suits is more rigid, meaning it will give more support. High-waisted briefs hide a multitude, as does a long-line bra. The 1950s silhouette suits you best and it has never been more in fashion so don’t restrict yourself to a one piece. Experiment with different cuts and colours and find something that makes you feel great.
