Although the thought of a sun-soaked day at the beach followed by a balmy evening by the marina seem out of reach right now, the summer months are fast approaching. While some of us may be lucky enough to avoid a period during our beach holiday, many have no choice when it comes to mother nature. Thankfully, there are countless options to help save your vacation - and no - we're not talking about tampons. Enter: period swimwear.

Say goodbye to surprise leakages, and say hello to fuss-free periods, period swimwear exists in all shapes and sizes, and it's a summer holiday game-changer. It's easy to question the practicality of period and leak proof swimwear as it almost sounds too good to be true. But, thanks to moisture wicking, multi layered designs, period swimwear successfully helps prevent any leakages, allowing you to have a carefree day at the beach, or pool.

Grazia's best period swimwear, at a glance:

Editor's pick: Modibodi One Shoulder Swimsuit, £59 on Modibodi

Best value: Love Luna Period Swim Briefs, £18 on John Lewis

Best for heavy periods: Modibodi Swimwear V Neck One Piece, £74 on Modibodi

While period swimwear may seem like some form of sorcery, there are indeed limits to how much each anti-leakage bikini brief or swimsuit can hold, and most briefs will stipulate whether they are designed for heavier or lighter flows. If you have a super heavy flow, fear not, as there is leakage proof period swimwear designed for you. The trick? Knowing where to look.

Whether you're looking for the best bikini or the best swimwear for big boobs, you're sure to find one that's also totally period-proof.
