A saucy lingerie company asked its female office staff to turn up in their undies for a day - and almost all of them actually did.

Taiwan's Audrey Underwear decided to celebrate record sales by naming November 21 Camisole Day.

All 500 female workers were encouraged to wear smalls - and a stunning 90 per cent did.

"We have been waiting for this day all month. Today, we are super high, and don't know where to put our eyes," salesman Cai Mingda said.

Mother-of-two Zhang Yufeng, 32, admitted: "I have been on a strict diet to get ready for the day. When I was trying on my outfit at home, my husband told me I should dress like this every day."
