The perfect lingerie

More than 70 per cent of us wear the wrong bra size. Try to make time for a professional fitting every few years or after any change in weight, exercise routine or hormone levels. No fitter nearby? Here's how to measure: Take a snug measurement around your rib cage directly under your bust, where the lower band of your bra sits. Be sure the measuring tape is smooth across your back and level at the front. Add five. For example, if you measured 29 inches, your band size is 34 inches. If the resulting measurement is an odd number, for example 33 inches, go to the next higher even band size (34 inches) or the next lower even band size (32 inches).

Take a loose measurement around your bust at the fullest point. The difference between this measurement and your band size is your cup size. Each inch equals one cup size. For example, if your band size is 34 inches and your bust measurement is 35 inches, your cup size is A.
