Andy Chow leads a double life. During the day, he is a 28-year-old architect working for a firm that specialises in hospitality design. At night and on the weekends, he runs a small, thriving business selling vintage clothing via the internet, pop-up shops and in the living room of his flat in Causeway Bay. His business, Standard Vintage, is devoted to Japanese clothing from the 1960s to the '80s.

Hong Kong born and bred, Chow developed a passion for vintage clothing - and furniture and home accessories - when he was an architecture student in Sydney. 'It was a discussion on Eames chairs that really ignited my love for vintage,' he says. After his bachelor's and master's degrees, he moved to San Francisco, where he discovered thrift stores and boutiques. 'I started selling what I found on eBay in the beginning,' he says. With two-year-old clothes that are simply outdated and out of fashion being called 'vintage' these days, Chow says he applies the term only to something that is at least 25 years old.

On his sourcing trips , Chow has also managed to build a wardrobe for himself with special finds such as a Kansai Yamamoto sandy suede jacket, a feather grey Burberry trench coat with the name of the previous owner on the label, and a plaid toggle coat from the now defunct Example by Missoni label. His most prized piece, however, is a chartreuse Moschino blazer embellished with what looks like potted flowers . 'This is my absolute favourite. I wear it all the time. I would never resell this,' he says.
