Waist: your natural waistline above your belly button and below your rib cage
Bust: the fullest part of your bust at nipple level

"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!"
"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."
"I've seen these bathers many time on my FB feed and I finally brought one. I then brought another in a different colour on sale, so a perfect way to try them out. They are truly as amazing as they say. I'm a 12/14 and brought a large great fit. I have never been one to wear a one piece before always board shorts. This one piece gives good coverage while still feeling feminine with the v neck."
"I purchased the Coolum one piece bathers online with some trepidation given my specific requirements for coverage and support and the fact I usually have to try on dozens of bathers before finding the right one. I was delighted when they arrived and were the perfect fit, offering great support whilst being flattering around the tummy area and high cut at the sides so they don’t cut me off at my widest part. They feel secure in the surf and are a win all round!"
"I am VERY happy with the swimmers I bought. I haven't swum in them yet, but they fit very well and are solid and well made, so should last well. I was concerned M would be too large, but though I am generally 10-12, it for perfectly. I look fwd to trying them out at Lake Ghula in Woodford soon."
"I bought this pair in an XL. They were a little loose so decided to purchase the size smaller. Thank goodness there was a sale on. Much better clingier fit even though I used the measuring information for the first pair. Haven't swum in them yet. Waiting for their first dip in Bali, early October. Love the design as they don't make me look like a frumpy old woman. And I can say that as I am in my senior years. 😜"
"Great fit and comfort. I usually feel very self conscious in swimsuits but now confident to be seen in bathers. I like that the material has texture and give , caters to individual shap. Very happy with purchased and price."
"Fabulous swimsuit on. Excellent stomach control panel and the sizing is accurate and it fits really nicely. The fabric is thicker than I am used but that means it will last and continue to hold its shape well for many seasons. The only downside is for us less endowed there is no padding as the designer made these for ladies with a decent chest. Personally I could use a bit of reinforcement. :) That aside I would buy another pair in a heartbeat."
"I love the fit on this swimsuit and it looks great. I'm a 34DD and a size 10 and I ordered 10/12 and it fitted perfectly. The material is very good quality and the colour is gorgeous."
