EXTRA HELP - RASHGUARDS:

Our rashguards are designed with a relaxed, classic tee style fit through the body - as shown on our model. Your usual t-shirt size works best for most customers.

A few things worth noting:

  • The fit is relaxed through the torso, more streamlined through the arms and shoulders.
  • Fuller or more muscular arms - size up for more room through the sleeves.
  • Prefer a firmer fit through the torso than shown - size down.
  • Bigger cup size - no need to size up. The design and four way stretch fabric accommodates beautifully, and we have loads of customer feedback confirming this, including from customers up to an 8G cup (wearing our XS).

Our model for this garment, Alice, is a size 10, 181cm tall and wears size S.
On some other styles you'll see Amber, who is a size 6-8, 171cm tall and wears size XS. 

ACTIVEWEAR BATHER TOPS:

True to size - go with your normal sports bra size. 

A few things worth knowing:

  • For a bigger cup size, use your bust measurement against the chart as your primary guide. Our four-way stretch fabric and generous cut accommodate well.
  • Not sure? We're happy to exchange or return within 14 days as per our Returns Policy.

Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.

ACTIVEWEAR BATHER BOTTOMS:

Generally true to size.

A few things worth knowing:

  • Slim waist - size down, as the waistband is designed with a fuller waistline in mind.
  • Between sizes - size down.
  • Four way stretch fabric gives a comfortable, flattering fit without being restrictive.
  • Not sure? We're happy to exchange or return within 14 days as per our Returns Policy.

Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.

LONGLINE SHORTS:

True to size - go for your normal shorts size.

Designed for intentional length and volume, in a classic Bermuda short style. Great for paddling and throwing on after a swim while you dry - but they're designed to swim in them too.

Our bathers are modelled by Alice, who is a size 10, 181cm tall and wears our size S.
