August Society Size Guide - Women

Our women's pieces go by international sizing standards.

A note on rash guards - we've received feedback that the sizing runs small. We design our rash guards to be snug to prevent drag in the water, but understand some like them looser. We recommend sizing up if you'd like a looser fit.

Women's swimwear size XL and XXL coming in spring 2022!

    Wonderful, comfortable rash guard (that also made me feel pretty)

    I loved it. I took it out for a Stingray session, and it worked so well. It wasn't hot to be in, even with the bright sun, and in the water, it was snug and comfortable. I felt well-protected from the elements.

    Attractive high quality rash guard

    I bought this for my daughter who has not used it yet but it's great that you produce sizes for petit girls. I feel there is a lack of choice for attractive full-zip rash guards in Singapore as most of the ones I have seen are rather plain and in dull colours

    Awesome Due South Blue Rash Guard

    Hi Toni What I like most about the Rash guard I last purchased is the fact that it is not heavy and draggy when it is wet. It still remains very much comparatively light weight when wet versus other off the shelf swim wear that I have on hand. It also drys much faster. This fact about it being comparatively light weight even when wet was the most outstanding feature besides comfort, convenience etc etc... Of course, I like the design and cut too!

    Excellent service and rashguards

    Great service from Toni! As the sizes are running quite small, i had to exchange both sizes bought with a bigger size. The replacement piece came very promptly after i submitted my request for change. The lagoon colour is bright and nice!

    Size runs small

    The size chart says S is same as U.S. 6 which is not. It is more like US 2-4.
