Young Teen College Girl Without Brassiere

Material and styles
Bras are typically made of a fabric including cotton, polyester, Spandex and lace. The cups may be supported by underwires made of metal and sometimes coated in plastic. Strapless bras usually use underwire to support the breasts. The underwire shares the breast weight with the shoulder straps.
Wirefree bras support breasts using strengthened, larger cups and wider bands. These bras are sometimes referred to as softcup bras. The bra is usually fastened with a hook fastener on the band, typically at the back. In some bras the fastener is in the front, between the cups. Others are pulled on over the head and have no fasteners. Some bras contain padding to improve comfort, conceal the nipples, or enhance bust size. Bust size and cleavage are also enhanced with breast pads inside the cups and by wearing push-up bras.
