Silverstone will replace Filipina models China and Mai-Mai Cojuangco, daughters of a Philippine sugar baron. Last year, the pair featured in a long-running print and television campaign shot in Italy.
Silverstone's endorsement is designed to facilitate Kamiseta's expansion to Europe, the US, and Japan. Roque said he has had franchise enquiries and hoped to expand there within the year.
Kamiseta has 30 branches in Manila and six branches outside the city.
Despite the economic slump it registered 30 per cent sales growth last year. Its line consists of women's casual wear and accessories for young female. Prices average US$14.
