Improve your body shape! Buy the right bra

Lingerie experts believe that 80% of women are wearing the wrong bra. Beat the trend by following our guide and get it right.

Remember, many a gorgeous outfit has been let down by the wrong underwear, so it's worth investing some time in your purchases. The right buy will help upgrade your look and guarantee red-carpet glamour.

Always have a bra fitting before you buy - professional fittings are available in most high street department stores as well as at specialist fitters like Rigby & Peller.

Bad-fitting bra: common problems

1.Saggy boobs - the back size is too large; not giving you the support required

2.Double boobs - the cup size is too small, which is when overspill occurs

You wouldn't wear the wrong size shoes, so why have a bra that doesn't fit? Wearing the wrong size bra can affect your posture, your confidence and spoil your silhouette. As with shoes, always try before you buy. Bras differ from shop to shop and style to style, and your bust size can change over time.

A good-fitting bra should be comfortable, supportive and give you the best shape under clothes. A correctly fitting bra should sit firmly but comfortably around the body. Underwires should lie flat against the ribcage, and contain the whole breast. The breast should be contained within the cup with no puckering or bulging in the cup fabric.

You are wearing the wrong size bra if:

Breasts are being squeezed out of the cup, creating a double boob effect

Breasts are not fully contained within the underwire, resulting in wires digging in or boobs dropping out under the wire

The underband is not sitting level at the front and riding up at the back

The underwires are standing away from the body

Breasts are unsupported and drooping forward

The shoulder straps are digging in

You are wearing the right size bra if:

The underband is firmly anchored around the body, and is level at the front and back

Breasts are fully contained within the underwire

There is no puckering or overspill

The underwires sit flat against the chest wall
