Because lycra is so stretchy, each size will fit a large variation of body shapes and sizes.
The table below shows the range of measurements for each size. The table will help you decide which size is best for you. Remember that you might be a different size for the top versus the pants.
As a rule of thumb:
Our Small size will fit women who normally wear a NZ / AUS size 10;
Our Medium size is equivalent to a NZ / AUS size 12
Our Large size is equivalent to a NZ / AUS size 14
Our XL size is equivalent to a NZ / AUS size 16
Our XXL size is equivalent to a NZ / AUS size 18 +
If you are between sizes, try the smaller size first - our sizing tends to generous and because this is swimwear, it needs to be on the firm side rather than loose.
And if your order doesn't fit, simply return for an exchange or a full refund - you pay only for the postage of the garment(s) you return :)
