The More of Me to Love Bra Liner is the premier bra liner and part of the "Love Your Clothes Again" line. This incredible bra liner is top quality, made of cotton, and is comfortable and machine washable. The liner is held in place by the tension of the bra or the weight of the breasts, and it wicks sweat, prevents irritation and chaffing and makes wearing bras a far more comfortable experience. Because there are 3 liners in every pack, you won't have to do the wash every day, though, you could since they are all machine washable. The size should be selected based on the bra size you wear. Our bra liners are designed to run from either side of your body - not all the way around. Available in 4 color choices: Black White Beige Neapolitan (1 Black, 1 White 1 Beige) Available in 5 sizes: Small (Liner length 14 in / 36 cm) Medium (Liner length 18 in / 46 cm) Large (Liner length 26 in / 66 cm) X-Large (Liner length 30 in / 76 cm) XX-Large (Liner length 36 in / 92 cm) To determine which size you need, measure the distance between your arms going beneath the breasts. This should be essentially half of your bra size. Please see the image of the sizing chart. The band is approximately 2 wide, increasing to approximately 4" in the front center of the band.
