The popularity of seamless bras is easy to understood since they don't show under your clothing. Seamless bras may be either contour padded or padding-free, with a smooth, seam-free cup. And they can be constructed with or without underwires. Lace trims are usually reserved for neckline, undercarriage and sides and back to leave the cups smooth and unadorned. Seamless spacer foam cups are a favorite for warm weather wear, as they breathe and are more comfortable. Push-up cups are frequently seamless, with the added benefit of graduated padding in the lower cup to boost "the girls." Full Figure DD+ and Plus Size women will love the "no show" aspect of cups without seams, giving them a sleeker look under clothing, especially minimizers that minimize size rather than shape. Racerbacks are popular, so you can look sleek under knit tops with cut-out armholes. Every woman should have several seamless cup bras in her lingerie wardrobe.
