A Time of Reckoning for Southeast Asian Fashion Brands

Southeast Asia is poised to reach US$53 billion in online retail by the year 2023, with a compound annual growth rate (CAGR) of 23%[1] fuelled by a growing middle-class population as well as high internet and smartphone penetration.


Fashion Leads Category Growth

While consumer electronics remains the largest category in the region, fashion (including apparel, footwear, and accessories) and cosmetics are forecasted to be the key drivers of future growth, mostly due to the lack of availability of brands in offline retail channels.

Zalora, the fashion e-tailer with a strong foothold in Southeast Asia, reported that sales doubled every year since taking part in Singles’ Day in 2014. Site traffic and items ordered tripled in 2018 compared to the prior year, as shared by Giulio Xiloyannis, Zalora’s Chief Commercial Officer, in an interview with South China Morning Post.


Trend Analytics Drive Growth Opportunities

With a positive industry outlook and growing online channels, fashion brands are now powered with retail and consumer data that is tracked, collected and managed through own websites, external sites and social media. The data, when layered with structured analytics and examined in detail, offers excellent insights to inform decision-making and devise strategies.

Trend analytics enables one such process that significantly influences fashion design and buying, with insights on a specific style, silhouette and colour direction up to 95% accuracy[2].

The birth of Mr P. by Mr Porter and 8 By Yoox are testaments to this. Both retailers utilise transactional data to spot bestsellers and product opportunities and combine it with an eye for design to execute buys for their respective in-house labels[3].

Trend Analysis vs. Forecasting

While more retailers in the US and UK are optimising trend analytics to chase “bestseller” re-ordering and to leverage on current demand momentum, Southeast Asia region is falling behind on digitisation and deploying analytics. Retailers who do not adopt the required changes to meet consumer demand will rapidly lose out in market share. Here’s why:


A trend forecast provides broad trend concepts which typically only commercialise in the next two years or more. This framework brings about high risk with low accuracy (less than 30%)[1] due to the long timeframe to mass adoption and the high dependency on intuitive interpretation of concepts (Chart 1). On the other spectrum, trend analytics incorporates data to provide insights on current product performance, supporting informed decision-making. This includes the decisions to chase an opportunity, to repeat a bestseller or to design a new collection. The influence of intuition is minimal, hence lowering the risk of overstocking while maximising profit.


Consumers today have greater access to the fashion industry than ever before. Hence, they are able to communicate and drive tastes through social media and across geographies, in real-time. This calls for an approach that analyses demand from a consumer behaviour perspective, than top-level macro predictions. As the industry gets more complex and competitive, these trend forecasts have not changed even though we now have so much data about consumers. Referring to these one-size-fits-the-industry reports on what to make next is no longer relevant.

Case Study #1
Animal Prints – The Importance of Right Timing

Animal prints had a strong presence in Fall/Winter 2018 fashion weeks, which took place in the spring of Feb 2018. Spring/Summer 2019 runways observed recurring animal prints, but by then, the trend had already reached the masses, as seen on the high street and social media.


Data Signals on Trend Movement

Omnilytics software analysed more than 400,000 data points from five of the top fast fashion retailers – ASOS, Zara, Boohoo, Mango and Urban Outfitters, to find 22,179 animal printed new-in products in the US and UK on a growth trajectory over the past 14 months (Chart 2)[1].

The animal print saw new-in lifted steadily in spring 2018 and peaked by summer, before growing aggressively to its culmination by the holiday season. In seeing the rise in April, and with the trend supported by fashion weeks, brands with efficient supply chain management could have developed animal printed styles and launched by July. In another scenario, retailers could have optimised the animal prints it had in stock to execute visual merchandising and marketing to show that they were tapped into the latest fashion trend.

For brands who had missed the data signals, they not only failed to achieve early commercial success but also ran the risk of over-stocking to markdown if they had launched the trend in the later seasons.

Case Study #2
Ultra Violet – An Underwhelming Offtake

Announced by Pantone® as 2018’s colour of the year, Ultra Violet gathered great hype as it arrived at an opportune time with the colour purple historically associated with efforts to achieve gender equality. However, despite publicity including colour applications across industries as published by WGSN, Ultra Violet did not take flight as predicted.


Data Doesn’t Lie

Omnilytics software ran an in-depth analysis on the vivid colour spectrum at the top 10 fast fashion retailers[1] and revealed that the highest newness came in vivid red, termed by Pantone® as Valiant Poppy[2]. While both colours achieved decent sell-out rates over 12 months in 2018, there were 3,558 new-in products launched in Valiant Poppy, compared to just 127 new products in Ultra Violet (Chart 3).

With trend analytics, a buyer can tactically approach stocking Ultra Violet by only selecting the bestselling styles in small quantities, while confidently order Valiant Red and Russet Orange as these came through for the dominant colour story. Buyers/merchandisers can also look at historic data to see how Ultra Violet has performed and how it has been discounted over time.

The State of Mass Market Adoption: Southeast Asia & 6-Month Opportunity

With internet penetration growing at a rapid pace, Southeast Asians can now access fashion events and pop culture happenings at the same time as the rest of the world. However, there is still an adoption lag.

Consumer Readiness

Global trends, driven by progressive design, are not adopted as quickly by Southeast Asian consumers, compared to their Western counterparts, for several reasons. These include the high price tags on designer pieces, the fact that some trends are not tropical weather friendly, or deemed unbefitting to the majority of modest consumers.

As a result, brands in the region only adopt trends about six months after a wider global adoption and reaching massive commercialisation (Chart 6).


The Silver Lining

The 6-month gap presents a window of opportunity for the local retailers to research and identify a particular trend’s much talked about products, and then produce in time for adoption by the “early majority” in this part of the region.

With trend analytics, fashion buyers can speed up this process by analysing the relevant market leaders, such as ready-to-wear designers or brands from the UK, US, Korea or Japan, to identify bestsellers in terms of style, silhouette and colour.

The State of Mass Market Adoption: Puff Sleeves & 6-Month Opportunity

Spring/Summer 2018 in the UK saw the rise of the ‘90s puff sleeve in street styles, and the trend continued into Fall and onto Spring 2019 with more prominent designs across tops, dresses and jumpsuits. As recently reported by the Standard Evening, it is clear that the trend shows no signs of slowing down.

In analysing over 350,000 data points at market leading retailers (Zara, ASOS, Shopbop in the US and UK) and Southeast Asian homegrown brands (Pomelo Fashion, Love, Bonito, Bobobobo), Omnilytics software is able to swiftly identify critical insights for the puff sleeve trend.


Spot Bestsellers Ahead

Southeast Asia seemed oblivious to this trend until as late as in Mar ’19 (Chart 7), carving out a clear 6-month path of opportunity.

Observing the new-in movement of the market leaders (INT New-In metric in Chart 7), if Southeast Asian brands paid close attention to the trend starting last year, they could have seized early potential opportunities.

Production capacity could be booked ahead, assortment range planned, and final designs could be tweaked and executed based on bestsellers, as analysed at the market leaders.

The Shifts in Consumer Demand

Fashion is traditionally based on forecasts and intuition. Editors highlight what individuals on the street should wear, while designers dictate the look and feel of a range, and buyers curate an assortment based on future consumer demand, all backed by little or no data. However, fashion today is seeing continuous waves of changes led by the shifts in consumer demand.


Consumer is King

With the growing power of social media and influencers, trends are increasingly established by consumers as opposed to retailers, editors and forecasters, flipping the control from an industry that pushes products out to its consumers, to an industry where product is pulled by the consumer. Therefore, understanding actual consumer demand is vital.


Getting the Right Product, Fast

Not only do today’s consumers want trend-driven products, at low prices, they want them quickly too.

Retailers who fail to recognise the value of getting the right product quickly, or are slow to react to the right trends, will lose out in sales- and eventually market share. A dynamic supply chain supports reordering or “chasing” into bestsellers in the current selling season, or producing a collection to get to market in 3 months or less.


content image-8 Fashion Trends: Analytics vs. Forecasting


Retailers have been referring to trend forecasting as a source of fashion inspiration as early as the 1960s. However, given the broad concept narrative and longer-term predictions, trend forecasting inspires only intuitive-developed themes of new fashion collections, while risking investments in the hope of scoring more commercial hits than misses.

With trend reports offering shorter-term predictions, design inspirations become more apparent. However, significant risk remains present when it comes to commercial interpretations of the runway designs and launch timing, as presented in the earlier case studies.


Trend Analytics Powering Fast Fashion

As the retail landscape gets increasingly competitive across segments and channels, every retailer, fast fashion or not, should invest in innovative tools and technologies to drive speed and efficiency, determining what can deliver the quickest return on invested time and money.

With data-backed trend analytics proving to accurately meet consumer demand with increased speed and a higher probability of success, the quintessential question every retailer should be asking themselves is, “will my business sustain and grow if I choose to remain status quo, walking away from potential profit gain?”. Reinforced with the 6-month path of opportunity, Southeast Asian retailers have no reason to walk away.
