Tulloch travelled to Yokohama, Japan, last month, to show an exhibition, called "Attitude", of collaborative work between herself and Christchurch sculptor Graham Bennett.
The exhibition was at Galerie Paris, during the city's triennial art festival.
The pair's exhibition also featured, in English, in a Japanese art map which was distributed throughout the city during the week.
Tulloch said the exhibition was a resounding success. It far exceeded her expectations, she said.
Japanese women took to her designs more than she had expected. She sold tens of thousands of dollars' worth of clothes.
Mild Red, which was established in 1995, had had continued interest from buyers in Europe. That there was such an "enthusiastic response" from Japan was another string to the company's bow, she said.
While in Japan Tulloch also met promoters and store owners, and hoped that within the next year she would stock her clothes in Tokyo stores. The Galerie Paris has ordered her winter 2009 range with a large increase in the items ordered.
"It could be huge if we wanted it to be," she said.
In 2010, she will go back to Japan to work with a calligrapher who saw her work and offered to help her create new designs.
