The impact of our work is reflected in the impression and satisfaction that our clients get and share with the market. They are the ambassadors of Performance.

“Performance has been accompanying us successfully for many years. Its staff, like an interpreter, know how to establish a link between factories and clients, facilitating the exchange of information, taking into account the context and specificities of each.

The team is a precious ally on a daily basis. Not to mention everyone’s undeniable sense of humour!”

“In 2012 I was lucky enough to meet Herminia and the factories she represents, when I started at ISABEL MARANT as a production manager.

During 10 years of collaboration within this house, we have developed together several product categories (finished products, jersey, tailored products), always with the same concern for detail, service (both in terms of price and quality, and in terms of timely deliveries). It has always been and continues to be a pleasure to go to Porto and meet the factories that I now know very well.

Herminia and her team are passionate people, driven by a sense of duty to do well and find solutions to solve every problem.

It is a real luxury to be able to count on an agency of this quality in Portugal, for ready-to-wear!”

“Performance and its partners have been reliable and quality partners for many years in all the fashion brands I have worked with.

I am infinitely happy that your first season with MARCIA is the sign of a long and fruitful collaboration.

Emma and Clara are loving people who will always be a great pleasure to work with.

Thank you a thousand times Herminia for the trust and friendship you have given me over all these years!”

“The Performance team, led by Herminia, as well as the partner factories, have been for me, during the last 20 years, reliable partners – agile, inventive, available, in the development of the manufacturing of products of excellence, respecting irreproachably the creative vision, the planning, prices, targets, and quality!

From the Kenzo years in Paris, to Saint John in California, this beautiful collaboration continues!”
