"I’m a size 8 but with a 66 yr old DD/E bust. Haven’t worn the cozzie in the water yet but appears to be a good fit and keeping “the girls” happily in their place. My only thought to improve my fit would be a bit more bum coverage as my bum is now really flat and could be a bit more supported. I have purchased two Coolum one piece at great sale price and a Coolum Tankini top has also just arrived - yet to try."
"While I’m yet to wear my swimsuit in the water I’m very happy with the fit and comfort, and I love the colour. I took the advice to choose the smaller size, however I’m pleased with the coverage, which is challenging to find when you have a bigger bust (F cup). The style is flattering too, which is a nice change!"
"I’ve seen Active Truth bathers reviewed by influencers but wasn’t sure if their views were genuine. I needed new bathers for our next holiday, I purchased two pairs for $50 each. Honestly, I have never felt so comfortable in bathers before! The cut, colours & fabric are perfect! 🙌"
"This is my first pair of Coolum Core Support one piece bathers and I am pretty happy with them. The fabric and colour is great and is good quality. I felt supported in the bathers, my only criticism is the bottom rode up a couple of times while I was doing my Aqua aerobics class. Maybe if the bottom had a slightly better coverage that would be better. Even though, I will buy these bathers again."
"Beautifully made, stylish design ! Love the lining and the thick fabric…great confidence booster. The ruching is always a winner in my opinion. It creates a slimming silhouette without compromising comfort. The fit is perfect but as I’m very short through the torso I had extra length in the bottom… easily fixed by my seamstress. Love these bathers so much I have ordered another pair today. I have recommended this brand to several friends already !"
"I love these swimmers! They fit beautifully without creeping up at the front or back, so much so that on holidays recently I was comfortable walking around the pool without feeling like I needed to scamper quickly to a towel or my room. This purchase was my second however there was a fitting issue with them. The excellent customer service and fast response from this company was amazing. I now have another pair which are fantastic- can’t wait for some warmer weather here to wear them. Highly recommended"
"I bought 3 as the fit is amazing. Keeps you supported without taking away from comfort. Do not ride up in the surf and they look appropriately elegant. They aren't thick persay but rather they aren't microthin like most swimwear. I have worn them all last summer and looking forward to the pool this summe"
"I often take a size larger than my measurements for swimwear (I hate it when things cut in) so I tried a medium first. It really was too big unfortunately and I couldn't return it because it was final sale - but I passed it onto a friend and she loved it! Then I bought the size down in the red colour and it was perfect and very flattering - I've worn it several times already. So, happy ending. :) FYI I'm 171cm and 57kg (S)."
"I have this in 3 colours now, holds everything where it needs to be,. I'm a 10F cup size and I'm the M fit is fantastic, have been wearing all summer, everyday and washes well"
"After going to buy multiple times I finally pressed purchase. I am not disappointed, they did fit perfectly. They feel firm, all my wobbly bits are contained. Colour is great. I’m a sixteenish, boobs probably size 18. 16-18 was the correct size."
