O'Neill Girls' Square Neck Swim Set is a girls' two-piece swimsuit made for beach days, pool time and warm-weather travel. It is designed with a close-to-body swim fit, so shoppers should compare body measurements with the listing's size chart before choosing a size. Also review the garment measurement or dimension images included in the listing, especially when deciding between adjacent sizes or comparing coverage expectations. The set features a square neckline and tank-style top with seamed shaping for a clean swimwear look, paired with a coordinating swim bottom. Coverage and removable cup details can vary by size or release; some variations are listed with medium coverage, while others are listed with full coverage, and select releases specify removable cups in sizes 10 and up. The stretch swim fabric is 82% recycled polyamide and 18% elastane, giving the suit flexible comfort for swimming, playing and relaxing near the water. This girls' square neck swim set is a versatile choice for beach, pool, lake, resort or vacation wear and is neutral enough to mix into current and future swim rotations.
