Setup: When putting on the Wonderbra Ultimate Plunge Bra, ensure that your breast tissue is fully scooped into the cups and positioned correctly within the `patented hand support` structure. Adjust the shoulder straps to provide comfortable lift without digging in, and ensure the band sits firmly and level across your back. A proper fit is crucial for maximizing the cleavage effect and overall comfort. Compatibility: This bra is specifically designed for deep V-necklines, plunging tops, and dresses. It will perform best and be most aesthetically pleasing with garments that feature a low cut at the front, making it ideal for evening wear, cocktail dresses, or specific fashion statements. It may not be the most practical choice for higher necklines or everyday casual wear. Care: To preserve the integrity of the foam cups and the `patented hand support` technology, hand washing is highly recommended. Use cool water and a mild detergent. Gently squeeze the water through the fabric, avoiding harsh scrubbing or twisting. Rinse thoroughly. Reshape the cups while wet and lay the bra flat on a clean towel or hang it to air dry, away from direct sunlight or heat. Avoid machine washing, tumble drying, ironing, or bleaching, as these can damage the delicate materials and internal structure, compromising the bra's performance and longevity.
