Looking for swimwear that supports, sculpts, and actually fits your body? You’re in the right place. Whether you're splashing with kids, swimming laps or sun-soaking with friends, our swim collection is designed for real bodies and real life - from size 8 to 26, up to a G cup.
Let’s dive into your most-asked questions and break down the features of each of our customer-loved styles.
Swimwear FAQs – Answered
Q: What’s the cut of the bottom like?
All styles offer mid coverage bottoms -that sweet spot between cheeky and covered. No constant readjusting, no digging in, just confident comfort that moves with you.
Q: Are they good for long or short torsos?
Yes and yes.
-
Our Coolum Tankini Top is ideal for longer torsos or anyone wanting more midsection coverage without a one-piece.
-
Our one-pieces are crafted with stretch and adjustable straps to comfortably suit both longer and shorter torsos.
Q: Do they support a bigger bust?
Absolutely. All tops and one-pieces include a wire-free internal shelf bra with power mesh support that fits up to a G cup. Adjustable straps let you tailor the fit for extra lift and security.
Q: What if I have a smaller bust?
You’ll still get shape and support - our internal shelf bras offer lift and natural contouring. Removable padding options give you flexibility.
Q: How supportive are the thin straps?
Thinner straps on styles like the Byron Bikini Top and Coolum One Piece are still supportive thanks to reinforced shelf bras, quality stretch fabric and adjustability. Want more shoulder support? Opt for the Sorrento One Piece, which features thicker straps for added comfort and lift.
Q: What size is the model wearing?
Model sizing info is included on each product page or captioned in our social content. For personalised fit help, send your bust, waist and hip measurements to hello@activetruth.com.
Q: Do they come with padding?
Most styles have room for removable padding, though they’re designed to sculpt and support without needing it.
Q: Are the tankinis sold separately?
Yes – all separates are sold individually so you can mix and match your perfect size.
Q: Underwire – yes or no?
No underwire here - just clever design. Our internal shelf bras and supportive fabrics give you lift, shape and comfort without the dig.
Q: Is there tummy support?
Yes! Our swimwear features core support power mesh in the tummy area - smoothing and shaping without squeezing or restricting.
Q: How do I find my perfect size?
All our products come in sizes S-3XL (AU8-26).
Want to see how they look on real women across our full size range? Click here to check out our blog post where we showcase both styles on every size from S–3XL.
Take three measurements:
-
Bust: Fullest part of your bust
-
Waist: Natural waistline (above belly button)
-
Hips: Widest part around your hips and bottom.
And compare these measurements to our Size Guide
If you are between sizes we generally recommend you size down, unless you are above an E cup. If you’re an E cup or above you might like to size up.
