    Form and function - seamlessly combined

    I bought this swimsuit after much thought, as it was not the cheapest option (with the 10% discount it was still over a £100, which is the most I have ever paid for a cossie). I'd been eyeing up Deakin and Blue swimmers for some years, when their wonderful colour combinations and rather attractive retro/ vintage styling caught my eye in a magazine article. Since I recently moved three miles from a beach and was planning on a bit of sploshing about in the sea, I thought I would take the plunge (sorry!) and finally empty the piggy bank and buy one. I used the online sizing guidance, which helpfully directed me towards the Hendricks, size 12. (To give an indication of my measurements - which may help other would-be buyers - I'm about 5ft 2 tall, my bra size is a 32FF, my bust measurement is 98 cms, my waist is 77 cms and my under bust is 76 cms.) The Hendricks size 12 was a perfect fit. I've swum around in the beautiful briny sea in my new cossie several times and I've really enjoyed wearing it - lovely colours, flattering cut, very comfortable around the bust and bum. The material feels pleasantly silky to the touch, but seems robust and is fairly quick to dry. It looks like a costume which will last, so money well-spent. It would be great to see a version with a slightly longer 'short' leg or skirt too - which would tempt me to buy another. Thank you.

    Gorgeous swimsuit, stylish and resilient

    I would buy another one of these in a heartbeat. Expensive, yes, but well worth the money because of the superior material and colours. It looks and FEELS expensive.

    I go swimming every day and this swimming costume has been great. For someone who has curves it fits really well and I like the fact that the website has real women modelling them. Add the fact that they are sustainable - what’s not to love!

    Super comfortable

    For this style I had to go up a size - I wear a 34H bra and needed the 16 Hendricks to fit for my boobs. The 14 Hendricks is my usual size. The Sweetheart is really comfortable and has great seat coverage, no riding up at all. As always, the fabric is strong and supportive though soft to touch. Love these swimsuits and I can’t imagine buying any other brand now!
