To ensure the best fit and performance, wear the Wonderbra Ultimate Strapless Bra by first adjusting the band firmly around your rib cage, ensuring it sits level across your back. The unique `hand-shaped polycarbonate technology` works best when the cups fully encapsulate and lift the bust. Ensure the silicone strips lie flat against your clean, dry skin for maximum grip.This bra is specifically `designed so that you can wear any strapless outfit`, making it compatible with strapless dresses, tops, off-the-shoulder garments, and other styles where straps would be visible.For care, due to its specialized components like `polycarbonate technology` and `silicone strips`, it is recommended to hand wash the bra in cool water with a mild detergent. Avoid harsh chemicals, bleach, and machine washing, which can damage the delicate materials and alter the shape and effectiveness of the bra. Lay flat to dry, away from direct heat.
