Bandeau bras--a cross between strapless bras and a tube top--are popular styles for teens. They are less restrictive than traditional bras, can be worn to show under shirts and sweaters, and often come in trendy fashion colors. Bandeau bras also work under tees, tanks and strapless or sleeveless tops and dresses.
Designed to be pulled on and usually made without closures, bandeau bras do not provide much support and is probably not a useful option for larger busted women. But it is a great 'starter' bra for budding figures--offering modesty, coverage and wardrobe versatllity.
