FASHION chain Quiz is to continue international expansion plans after online revenue increased by more than 200 per cent in just six months.

Online revenue hit £13.8 million in the second half of 2017, fuelling an overall revenue boost of 35 per cent.

The Glasgow-based firm, which floated on the London Stock Exchange just three months ago, said gross margins are in line with expectations and the "strong growth" reflects its global ambition.

Founder and chief executive Tarak Ramzan said: "We are very pleased with the Quiz brand’s strong growth across target markets and channels with online in particular experiencing continued outstanding momentum."

With a presence in 20 countries, including key markets in both Europe and the Middle East, Quiz has grown from just one shop on Victoria Road in Glasgow's Southside in 1994.

It credits its recent success to strategic investment, including the opening of a 180,000 sq ft distribution centre on the outskirts of the city in summer 2016 and, more effective marketing and increased product ranges.

This includes affordable bridal and plus-size offerings, though the brand continues to specialise in evening and occasion wear.

Ramzan said: “Our IPO in July 2017 was a hugely important milestone for the company as we continue to build the Quiz brand as a global fast-fashion destination for customers who want the latest looks at outstanding value.

"The Quiz brand has a distinct USP, a strong customer connection and fast-fashion in its DNA.

"Our customer base is growing strongly and we are confident of delivering further growth.”

According to a pre-close trading update, group revenue rose to £56.1m for the six months until the end of September.

Sales through Quiz websites shot up by 122 per cent, with further trade achieved through third-party sites.

The brand launched its first localised e-store in Spain last month, following a tie-in with Zalando in Germany in May and with Next last October.

Further targeting the Spanish market, the group has opened three standalone stores in Madrid, its first outwith the UK and Republic of Ireland, where another branch will launch before Christmas.

Meanwhile, another 11 international franchise operations have been added during the six month period, including sites in Dubai, Morocco and the United Arab Emirates.

The group said this demonstrates "opportunities for the Quiz brand globally".

In the UK, where another five standalone units will open before Christmas, sales in shopping centre outlets and concessions jumped 15 per cent to reach £32.2m.

Four new concessions also opened during the period, but this was balanced by the closure of four existing sites and one standalone store.

Shares in the style specialist, which targets female consumers aged 15-35, climbed to around 197p on the morning that that it entered the junior market on the London Stock Exchange.

At the time, Ramzan said: "Today’s admission marks a significant milestone in the growth of the Quiz brand. With our unwavering focus on providing fantastic occasion wear and dressy casual wear at value for money prices, Quiz has a very exciting position in the fast-growing fast fashion market."

Responding to the new figures, Panmure Gordon analysts said they had a "high degree of confidence in longer-term forecasts" due to the "many attributes of a high quality business that Quiz possesses".
