Australian lingerie and sleepwear retailer Bras N Things will be opening its 200th store in Perth.

It will swing open its doors on 10 May at the Perth shopping precinct of Hay Street.

To celebrate, Perth shoppers will be sent on a city-wide lingerie hunt, whereby 200 mannequins dressed in the lingerie chain’s trademark briefs will be scattered around the city to be found. For every mannequin returned over the course of the day, Bras N Things has committed to donating $50 to the National Breast Cancer Foundation.

“We are thrilled to be opening our 200th store this May. It is a proud moment in the history of Bras N Things and a monumental achievement for the brand. We would like to thank our loyal customers for their support and look forward to continuing to bring them the best in lingerie and sleepwear for years to come,” CEO Nicole Noye said.

The first Bras N Things store opened in 1986. Since 1995 Bras N Things retail growth has notably expanded opening 50 stores every five years in prime retail locations across Australia and New Zealand.
