The Marina West Swim Take A Dip bikini in Hot Pink is a two-piece set with a twist-front top and high-rise bottoms. The current product gallery shows the twist at the center of the top and the bottoms rising above the navel on the model. The listing offers S, M, L, XL and 2XL, and says the style runs small: order one size up, including when between sizes. That instruction is useful, but it does not tell you which part of the set will be tight. Check your bust, natural waist and hip separately before treating the size-up note as a complete fit answer.

Start with three measurements, then locate the pressure point

Measure your bust at its fullest point, your waist at the point where you expect the high-rise band to sit, and your hip at its fullest point. Use a flexible tape without pulling it into the skin. If your intended waistband sits away from your natural waist, take a second circumference at that actual height. The listing does not say where its waist figure was taken, and the photograph cannot supply a body measurement. Compare the three readings with the source figures below. The source calls these “product measurements,” but does not explain whether they are body-size recommendations or finished-garment dimensions; ask before making a close fit decision.

For a worked example, suppose a shopper measures 35 inches at the bust, 28 at the intended waistband and 38 at the hip. On the printed figures, bust and waist fall between M and L, while the hip matches L. The listing’s size-up note makes L a reasonable size to investigate first, but it does not prove L will fit: the top band, cup shape and exact rise are unmeasured. Moving to XL would add 2 inches to the listed bust, 1.5 inches to the listed waist and 2 inches to the listed hip relative to L. That trade-off may relieve one area while making another looser. These are chart differences, not measured stretch or a personal size prescription.

Check the top and bottom for different reasons

The top has no underwire and lists removable chest pads. A removable pad changes the insert arrangement; it does not establish that the underbust band or the cup fabric can be adjusted to every shape. Ask for the top’s underbust measurement and how the back closes or adjusts if your bust number is between rows. The listing calls the fabric slightly stretchy, but gives no stretch range. If a current swim top fits your bust but presses at the band, compare that band separately instead of sizing from bust alone.

For the high-rise bottoms, compare the listed waist and hip figures with bottoms you already wear comfortably, especially when seated. The photograph shows a high front rise, but the listing does not give a front-rise height, leg-opening circumference or coverage measurements. If you need the waistband to reach a specific point on your torso, measure the distance on your reference bottoms and ask for the same garment measurement here. “High rise” names the design; it is not a fixed height on every wearer.

Make a short decision record before choosing

Write down your three body readings, the location of the intended waistband and the row that each reading points toward. Mark the area where your current suit feels tight or loose. If all three readings favor one row, use the runs-small note as a reason to check the next size’s band and coverage, not as proof that it must be ordered. If the readings split across rows, ask for finished top-band, bottom-waist and rise measurements. The set is sold as one selectable size, and the listing does not offer separate top and bottom sizes; resolve a top-versus-bottom conflict before ordering.

The listing specifies 83% polyester and 17% spandex, a solid Hot Pink option and cold machine washing with low tumble drying. It does not give a lining construction beyond “body: not lined,” an opacity test or water-use performance. The gallery is the best reference for visible color and shape, although screens and lighting can differ. Use the chart, the size-up note and the unanswered construction questions together so the choice is based on the part of the suit that matters most to you.
