O'Neill Sydney Floral Cinch Tankini Set
The O'Neill Sydney Floral Cinch Tankini Set delivers the coverage of a one-piece with the versatility of a two-piece. The tankini top features spaghetti straps, an allover floral print, and side cinch ties that let you adjust the length and silhouette for a personalized fit. Pair it with the matching full-coverage strappy bottom and the set is ready for the pool, beach, or ocean.
Built with Recycled Materials
The fabric is 82% Recycled Polyamide and 18% Elastane, giving the set a soft, stretchy hand feel with a conscience. O'Neill draws on decades of California surf heritage since 1952 to engineer swimwear that keeps up with active kids in and out of the water. The Elastane content provides four-way stretch and shape retention through repeated use and washings.
Top Design
The tankini top sits higher on the torso than a standard bikini top, providing extra midsection coverage that many parents and kids prefer. The adjustable side cinch ties allow the hem length to be customized on the go. Removable bra pads are included in larger sizes for added modesty and support as girls grow. The allover floral print runs consistently across both pieces so the set coordinates as a matched look.
Bottom Design
The full-coverage strappy bottom offers secure fit and confidence-boosting coverage for active movement. The cut sits at the hip and provides rear coverage that holds up through swimming, jumping, and beach play.

Frequently Asked Questions
- What is included in the O'Neill Sydney Floral Cinch Tankini Set?
- The set includes a tankini top with spaghetti straps and side cinch ties, plus a matching full-coverage strappy bottom. Both pieces feature the same allover floral print.
- Does the tankini top have bra pads?
- Yes, the top includes removable bra pads in sizes 10 through 14, providing optional modesty and light support.
- What fabric is the O'Neill Sydney Floral Cinch Tankini Set made from?
- The set is made from 82% Recycled Polyamide and 18% Elastane. This blend delivers four-way stretch, shape retention, and is constructed with recycled materials.
- Is the O'Neill Sydney Floral tankini good for active kids?
- Yes. The Elastane content provides stretch for movement, the cinch-tie top stays in place during activity, and the full-coverage bottom is designed to hold its position through swimming and beach play.
- What are the best swimsuits for girls for summer outdoor activities?
- A tankini set like the O'Neill Sydney Floral Cinch offers a practical balance of coverage and flexibility. The two-piece design makes changing easier than a one-piece, while the longer tankini top provides more coverage than a standard bikini top.
- How do the side cinch ties on the tankini top work?
- The cinch ties are located on each side of the top hem. Pulling them gathers the fabric at the sides, shortening the top's length and adding a ruched texture. Loosening them allows the top to hang at its full length.
