Women with plus size busts frequently don't care for a lot of thick padding, or any padding at all, which is where unlined bras come in. Plus sizes bras start at a 42 band, and the cup structure can vary from seamless minimizers to multi-part cut & sewn styles that impart shape. Because there is no padding, the breast is not obscured by other layers. However, there is no extra thickness to prevent "show through" in case that is an issue for you. Pullover knit styles without closures are popular, as are bandless front styles that also offer more vertical space for plus size petites and those with short torsos. There are several plus size sports bras that are unlined for a cooler feel. You will also find unlined plus size front closure, convertible and nursing styles in this category.
