Jantzen Cosmopolitan DDE Ruched Mesh Frill One Piece Black
Pickup available at Oz Resort
Usually ready in 24 hours
One of our best-selling Jantzen swimsuits, this beautifully supportive one piece is designed for women who want flattering shape, comfortable bust support and effective tummy control without sacrificing style.
Featuring Jantzen Trim Swim technology, the swimsuit uses strategically positioned PowerNet to provide additional support and compression through the front of the body. This helps smooth the tummy and create a flattering, streamlined silhouette while remaining comfortable to wear.
Supportive Underwire & Bust Shaping
Internal underwire provides additional bust support, while PowerNet cup construction helps shape and contour the bust.
A specially designed folded PowerNet wedge provides additional lift and shaping, making this an excellent choice for women looking for a supportive one piece swimsuit with a secure, flattering fit.
Tummy Control & Body Shaping
PowerNet support through the front of the swimsuit helps gently smooth and support the tummy area while enhancing your natural curves.
The result is a swimsuit that feels secure and supportive without looking overly structured.
Flattering Feminine Design
The V-neckline creates a flattering shape through the bust and décolletage, while soft gathering at the centre front adds further contouring.
A delicate double-mesh frill finishes the neckline and gives this classic Jantzen swimsuit a feminine touch.
Adjustable shoulder straps allow you to personalise the fit, while the regular pant cut provides comfortable everyday coverage.

How to Take Your Measurement
Use a flexible cloth or hemline tape measure to take your measurement accurately. If you do not have one, you can use a string as a measuring tool and then align with a ruler to retrieve the exact measurements. Measurements of actual garments may vary from style to style depending on the features and technology used.
Bust
With arms relaxed down at your sides, measure the fullest part of bust/chest, keeping tape parallel to floor.
Tip: With the tape in position, take a breath in and out, allowing it to slide to its most comfortable, non-binding fit.
Waist
Wrap the tape around your natural waist line. Measure around your natural waistline, which is the smallest area of the waist. This is normally found between the ribs and hips.
Tip: Remember to keep the tape measure slightly relaxed for a more comfortable fit.
Hips
Stand with your feet together, keeping the tape straight and parallel to the floor. Measure around the fullest part of the hips, where the top of your hip bones are located.
Torso
Start at your shoulder closest to your neck and take the tape down the front of your body and pass it under your crotch. Move it all the way up your back to meet the other end of the tape at your shoulder, it should look like a loop.
