When it comes to summer in Australia, looking effortlessly stylish relies on one thing above all others: swimwear. A great bikini can do double duty as a bralette under a sheer top on a balmy night out, a one-piece can easily transition into a bodysuit with a pair of breezy palazzo pants, a tankini (yes, it is back) looks 90s-chic worn with a low-slung skirt.

Investing wisely in a great pair of swimmers streamlines summer dressing, and also means you’re ready for a spontaneous ocean dip at a moment’s notice. Here, we round up our favourite pieces that make staying cool look effortlessly chic.

A one-piece that can double as a bodysuit

With its moody khaki hue, deep plunge neckline and low-cut back, Scanlan Theodore’s one-piece makes the perfect sultry bodysuit to wear to dinner. Pair it with wide-leg black pants and a pointed toe slingback for easy elegance.

A bikini to wear as a bralette

The stone detailing on Fella Swim’s Tony top makes it especially well suited for adding some extra interest to a crisp white shirt buttoned midway. Pair it with long shorts and a kitten heel for laid-back cool.

One-piece, two ways

Strapless one moment, with spaghetti straps the next, Zimmermann’s elegant textured one- piece easily transitions from beach to bar. Leave the straps on while you swim then easily slip them off for a sophisticated evening look.

A bikini for under a sheer outfit
