One of the defining features of this bikini top is its triangle halter design with self-tie straps. The adjustable neck and back ties allow wearers to customize the fit for comfort and support, while the sliding triangle cups can be positioned to provide the preferred level of coverage. 

This flexible design helps the top adapt to different body shapes and makes it easy to tighten or loosen depending on activity or preference.

The top is typically made from a soft, stretchy blend of polyamide and elastane, a fabric combination known for being breathable, quick-drying, and comfortable against the skin. 

The material moves naturally with the body and maintains its shape even after swimming, sun exposure, or repeated wear, making it suitable for long summer days at the beach or pool.
