Chief executive Justin Stead said: “All the foundations and investment that we have put into the business since the acquisition in June 2016 have paid off. With our redefined brand DNA, our evolving fashion-forward ranges, targeting a younger market and continued success overseas, the company is in a strong position.
“During the year ahead we will continue to capitalise on the success in the US through organic growth with existing partners and extend our reach with additional routes to market.
“Further afield, there is a clear opportunity for China to be a growth market, initially with Tmall, which has already shown a phenomenal sales trajectory.”
