What brands of backless bras are the cheapest?
Backless bras are widely known for being unsupportive, and
cheaper brands will lack the sophisticated techniques that the more
high end models use. Therefore, it is perhaps not a good idea to
choose a backless bra solely on price. However, the brand "Fashion
Forms" make low cost backless bras, or the brand "Unbra" is
available for as little as $10, although this only comes in smaller
cup sizes.
