    I ordered a size Large (I’m an E cup and they fit perfect, wouldn’t go smaller). The colour and material is so nice and vibrant, I love the overall fit! Review by zoe • (Posted on 4/12/2018)

    The top fits perfectly (even sizing up it doesn’t completely cover you) the fabric is so soft and comfortable, and the colour is so flattering and gorgeous. Definitely a new favourite! Review by Steph • (Posted on 5/09/2018)

    Absolutely obsessed with my new bikinis! I bought a pair of triangles and cheeky bottoms. I'm a size (Aus) 8 in tops, but (Aus) 10B/C in bras and the XS triangle was a bit too small so I'm exchanging for the S size which should fit perfectly. The packaging is super cute and as for the togs - the fabric is soooo soft and they are so damn comfy. I can't wait to purchase more in different colours! Review by Sophie • (Posted on 16/08/2018)

  • Note: this is a size GUIDE, as we are all different shapes and sizes, and few of us are the same size across different brands.

    Our bikinis are designed for minimal coverage, so we don’t recommend you go for a size smaller than you would typically be.






    AA or A



    D or DD

    Between two sizes?  Go for the larger size - our triangles are designed for minimal coverage; you don't need less coverage than that.
    Fit: Our Triangles have been designed to minimise tanlines, so are fit for minimal coverage.  Just like the classic triangle cut, ours have adjustable neck and back straps. The triangles aren’t fixed which gives you the freedom to wear them just how you like to! If you don’t like any side boob, add a size. If you have a small bust with broad shoulders, add a size.

    After more sizing tips or advice? Head to our sizing page for more information, or contact us via our chat/support on the help widget. 

  • We have an obsession with clean, minimalist bikinis that complement the female form.  This is our take on the classic Triangle bikini top.  It considers simplicity, comfort, tan lines and flattering cuts. 

    F A B R I C : we only use the softest, most luxe-to-touch swimwear fabric we can find. 

    P A D D I N G :  we do not use padding as it becomes heavy when wet, can take a while to dry out and the removable inserts rarely stay in place.  Instead, we double up on the fabric. Every piece is lined with the same luxe fabric as on the outside. 


    Our bikinis are proudly designed in Manly Beach, Australia. We hope you love them as much as we do!
