This black triangle bikini pairs a halter-tie top with a side-tie bottom, both printed in a bold orange and black monarch butterfly pattern. The top ties at the neck and back for an adjustable, minimal-coverage fit, while the bottom uses two long hip cords instead of fixed sides for a low-rise, Brazilian-style cut. Both pieces are cut without padding or underwire, so the shape follows the body rather than a molded cup, and the thin cords let you set the fit tighter or looser at the neck, back, and hips.

Monarch Butterfly Print

The wing pattern runs across both the top and bottom in orange, yellow, and black, mirroring a monarch butterfly's natural color break. The print sits centrally on the triangle cups and on the bottom's front panel, so the design stays visible even at a low-rise angle. This is a printed swim fabric, not an appliqued or embroidered design, so the pattern will not peel or fray at the edges with normal wear. The black background keeps the orange and yellow wing sections high-contrast rather than washed out in bright sun, and the same print is matched across both pieces so the top and bottom read as one set rather than mismatched separates.

Styling and Occasion

Pair this triangle bikini set with a sheer kaftan and flat sandals for a beach-to-boardwalk look, or add a denim jacket and layered necklaces for a poolside day-party outfit. It also works under a fitted rash guard for a beach day with more sun coverage on top, and the bold butterfly print reads well against both plain white cover-ups and bright resort prints.

• Beach or pool day: worn alone with a wide-brim hat and sunglasses
• Resort evening: layered under a sheer kimono cover-up with strappy sandal heels
• Boat or yacht day: paired with a cropped denim vest and gold layered jewelry
• Pool bar afternoon: worn with a straw tote and slide sandals

Sizing and Fit

The triangle top and side-tie bottom both rely on cord ties rather than fixed bands, so the set adjusts across a bust range of roughly 32 to 36 inches (81 to 91 cm) and a hip range of about 34 to 38 inches (86 to 97 cm). Because the top has no underwire or molded cup, it fits a smaller to medium bust best and gives less lift for a fuller bust; anyone sizing between two ranges should size toward the smaller hip measurement since the ties add extra adjustment room.

• Fits: A to C cup sizes, hips up to roughly 38 inches (97 cm)
• Not ideal for: a D-plus cup that needs underwire support, or anyone wanting full rear coverage
• Adjust: loosen or tighten the neck tie and both hip cords to fine-tune placement

Material and Care

Both pieces are made from a stretch nylon-spandex swim fabric that holds its shape after repeated wear in chlorine or salt water. Hand wash in cold water after each wear, skip the dryer, and lay flat or hang to dry away from direct sun to keep the orange and black print from fading. The knit has enough stretch to move with the body when swimming or lounging, though like most printed spandex blends it will soften slightly after many wash cycles.

• Fabric: nylon-spandex blend swimwear knit
• Care: hand wash cold, no bleach, no tumble dry
• Durability note: extended sun exposure will gradually fade the print, as with most printed swimwear
