From skimpy bikinis to cover-ups, body confidence on the beach or by the pool is all about finding 'the' costume style that doubles up as a silhouette miracle worker and makes you feel like Ursula Andress emerging from the sea.
Pick the wrong swimsuit and you could spend your holiday hiding behind a windbreaker or praying you'll blend into your beach towel.
Bashful beach babes can rejoice in the news that barely-there bikinis are out of favour for full-on swimsuit glamour with more coverage.
Dolce & Gabbana's spring/summer catwalk set the tone for retro corset-style swimsuits with low-cut legs, while Topshop Unique catapulted swimwear into the future with modern crossover cut-outs and geometric lines.
Bikini, tankini or all-in-one costume convert, this season there's a swimsuit for every body shape that will set temperatures rising even more than they are now.
Designer at Debenhams, Melissa Odabash, offers her figure-flattering shapewear tips to look sizzling hot on the beach this summer...
Celebrity triangle: Danielle Lineker
"As an inverted triangle you will have narrow hips and a slender waist with wide shoulders or a full bust," Melissa says. "Choose shorts, hipsters or detailed bottoms to draw the eye downwards. Pick swimsuits with a low cut leg for retro glamour."
Avoid: Avoid halterneck styles that will enhance your top heavy imbalance.
Celebrity hourglass: Kelly Brook
"You have a curvaceous body with a full bust and rounded hips, defined by a slim waist," says Melissa.
"Make sure that you keep prints or bold colours consistent on your top and bottom halves or choose clean, unfussy styles.
"Look for styles with control which will smooth your tummy but still show off your figure."
Avoid: Triangle bikinis that won't support your fuller bust.
Celebrity pear: Beyonce
"The classic shape, your figure has full, curvy hips and thighs with narrow shoulders," Melissa explains.
"Avoid low leg shorts and instead go for regular pants as these will give your legs an elongated appearance.
"Draw attention upwards with embellished necklines and prints and enhance shoulder width and create balance by sticking to halterneck styles."
Avoid: Side-string or print bikini bottoms, which will highlight your bottom half.
Celebrity rectangle: Cameron Diaz
"This shape is slim and slightly boyish, with slender shoulders and hips and little waist definition," reveals Melissa.
"Boost your cleavage with gel bikini tops and twist bandeaus. Layers of frills will add volume if you don't like padding.
"Go for swimsuits and bikini briefs with details such as ruching, bows or frills around the hips to create the illusion of curves."
Avoid: Vertical stripes, which will elongate you and make you look boyish.
