To use this bra set, simply put on the bra first, adjusting the straps for a comfortable fit. Then, slip on the matching panties. When it comes to care, always remember to hand wash this set instead of using a washing machine to prevent damage to the delicate elastics and hardware. After washing, let it drip dry naturally. Don't wring it or use a dryer as it may shrink or distort the shape. And make sure to refer to the fit guide if you're unsure about the sizing.
