It also noted that Singapore is the priciest place in the world to buy clothes, as malls and boutiques in its popular Orchard Road retail hub import luxury European brands to "satisfy a wealthy and fashion-conscious consumer base".
Singapore has one of the world’s highest concentrations of millionaires relative to its 5.4 million population. Its per capita income of more than $51,000 in 2012 masks a widening income gap between the richest and poorest.
