Denise is a self taught Eco Fashion Designer, who started designing up cycled "One of a Kind" fashions in 2008, taking discarded fabrics, denim and clothing and up cycling them into unique one of a kind designs".

In designing her fashion range, Denise uses materials from factories, thrift stores, garage sales and donations. She re-uses these fabrics and garments to make new "One of a Kind" fashion clothing. "My aim is to be kind to the environment with my business practices and to make sure that I purchase new materials required from sources where people do not suffer in the production process".

In 2013 Denise launched New Zealand Inaugural Eco Fashion Runway - NZ Eco Fashion Week to support other NZ Eco Fashion Designers and to give them a unique runway to showcase their collections.
