The experts agree.

Qin Qing, a senior etiquette consultant, says the ladies' intention to look their best is commendable. It is their choice of costume that is questionable.

The qipao, says Qin, can project an overly sexy image, which is not quite appropriate for such serious meetings.

So what is the proper dress code?

Qin advises female delegates to cover up. Low-cut necklines are a definite no, and leather skirts and furs should be avoided.

Leopard prints, overly elaborate jewelry and heavy makeup should be toned down. Elegant skirts or pantsuits are still the safest choices, but that does not mean dull or dark colors.

Pick from a spectrum of pastels such as peach or mauve, but avoid bright reds and neon greens or opt for darker maroons and taupe.

Accessorize with discreet brooches, sweaters or scarves - and when it comes to earrings, stay safe with studs.

Qin points to television celebrity Yang Lan as an example of good taste.

"Celebrities are better at handling the occasion. They're well trained in grooming," she says.

Sober colors like taupe or chocolate are good choices, such as the light camel-colored coat that Yang Lan (top right) wears. The army greens are still around, although the furs should stay home.
