Unlined bras have no padding - that's their main characteristic. And when they're paired with a wireless construction, that makes them even more desirable for some women who prefer less bulk and don't like the feel of a wire. Cups may be seamless or seamed, depending on your preferences, and whether you need the shaping of seamed cups. Unlined sports bras with compression fronts hold breasts closer to the chest wall, so still support the breasts for no-bounce wear. Many wireless, padding-free posture and post surgical bras feature tall backs to help support a fuller bust. Sleep/leisure bras fall into this category if they're padding-free. Women who are sensitive to chemicals will love Cottonique bras that are made of organic cotton. Look to HerRoom to supply all your unlined, wireless bras - there are perfect styles here for all women who prefer this combination.
