Glasgow-based fashion firm Quiz said on Tuesday its revenue rose 19% to £66.7 million in the six months to September 30 “despite challenging market conditions” while underlying profit before tax fell 11% to £4.2 million.

Quiz CEP Tarak Ramzan said: “Quiz has continued to deliver good revenue growth in the first half of the financial year despite challenging external market conditions.

“This performance was driven by further expansion across each of the brand’s distribution channels with particularly strong sales generated online through Quiz’s websites.

“The Quiz brand continues to grow, and we have seen good sales momentum in our core collections as well as across extended ranges including QuizCurve, Occasion and our newest range, QuizMan.

“Towards the end of the period we launched our second collaboration with TOWIE supported by the group’s first ever national TV advertising campaign.

“Quiz has a clear customer focus, a proven ‘test and repeat’ model and a dedicated management team.

“With these strengths, and despite a challenging market environment, the board believes the group is well positioned to deliver long-term profitable growth.“
