Oscar fashions are a challenge from the inside out

LOS ANGELES, Mar 7 (Reuters) It's what you don't see the stars wearing at the Oscars that really provides the va-va-voom on the red carpet.

If a star wants to turn heads, she has to start with what no one sees -- the perfect undergarment to build up the bosom or minimize the backside.

Lingerie has joined the gowns, jewellary and handbags lent or given to actresses by firms eager for the publicity associated with Sunday's Oscars and other awards shows. But there are potential pitfalls, whether an ill-fitting garment, or ill-mannered observer.
