"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."
"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 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."
"I was a cautious about ordering another swimsuit online as I’ve been burnt many times from companies when I receive them they are poorly made and cheap material. However this is not the case with Active Truth they are a true size fit and loving my mint green one piece. Thanks Active Truth"
"I have bought 3 of these now. All on sale so can’t exchange. The first one was the Sorrento. It was too big so I bought a smaller size, fits beautifully so I then bought the same size in the Coolum. It, doesn’t fit so well around the bust, less coverage. So out of 3 I have one great pair! Colours are all lovely. I’d definitely buy the Sorento again!"
"I love the cut, comfort and how flattering the Coolum Core one piece is. I have 3 pairs now, the olive green, red and black and I love them all. It’s a great confident booster when I slip on my choice colour of the day and know that I look great and am so comfortable. Thankyou"
"It's been a long time since I've felt this confident in a swimsuit. I love the flattering fit without feeling too tightly held in. Great for the hot weather, in the pool or on the beach. I now look forward to going for a swim. A great colour, not too bold to stand out although now I feel brave enough to order an additional one in a brighter colour!"
"What a terrific surprise when my Coolum swimsuit arrived. It's hard enough to get a good fit when ordering clothes online; but I had felt a swimsuit was going to be a big ask. However, the Coolum delivers well and truly. . . . a lovely fit and flattering design."
