COSSIE+CO was founded in 2018 by Isobel Elphinstone who set out to develop a swimwear collection with a single concept in mind:
Swimwear for the Modern Woman.


The COSSIE woman needs swimwear that can stand up to her lifestyle. Whilst a COSSIE is the embodiment of simplicity, and femininity, it is also a celebration of quality, colour, and fun; for all the places your COSSIE might take you (even if you never leave the back garden).

The signature honeycomb fabrication is synonymous with the brand. This fabric is double lined across all styles giving an element of natural support and a super luxurious feel. All styles transcend seasons and trends, creating a collection that is made to last; COSSIE’S that you keep coming back to year after year.

So, say no to wedgies, to that ‘can you see my .....’ moment, no to a nip slip, and no to holding in your tummy all day. Say yes to jumping from the boat's top deck, showing off your waterskiing skills, going from beach to bar and only adding a pair of shorts and lots of gold jewellery.

At COSSIE+CO, we don’t take ourselves too seriously but we do take our swimwear seriously.
