Measure your bust, waist and hips using the Active Truth size guide. Our one-piece swimwear is made to fit Australian dress size standards up to an 'E' cup in the bust for one-pieces and a DD cup in crop styles, if you are an 'F' cup or above we recommend purchasing the next size up.

Our model's clothing and bra sizes are listed on each swimwear item. We always recommend using your measurements to find your perfect fit, as numbered sizing differs so much between brands that it's difficult to calculate your size based on that alone.

Every size in every one of our products has been tried, tested and tailored on real bodies—we don't just 'upsize' our patterns.
