Next-Gen Fashion Trend Forecasting with Generative AI

Fashion trend forecasting is the process of predicting future fashion trends by analyzing consumer behavior, cultural shifts, market data, and industry dynamics. With the rise of social media and e-commerce platforms, trend forecasting has become more complex yet more critical than ever.

Companies in this space, like WGSN, Heuritech, and Trendee, are pushing the boundaries by leveraging technology to anticipate what’s next in fashion. While WGSN primarily relies on human experts and blends runway and retail data analytics, Heuritech focuses mainly on computer vision algorithms to analyze images but lacks deep textual analysis of cultural and emotional data. Trendee stands out as the first of its kind in developing a fashion-domain multimodal large language model (LLM), capable of analyzing text, images, and videos to provide comprehensive insights for trend forecasting.

What is Fashion Trend Forecasting?

Fashion trend forecasting can be categorized into two primary areas:

• Macro trends: These are long-term, slow-moving trends that reflect broader societal shifts. For example, sustainability and digitalization are two macro trends currently shaping the fashion industry, driven by global concerns over the environment and the rise of online fashion commerce.
• Micro trends: These trends are more short-lived and often driven by viral moments on social media. Micro trends like cottagecore, Y2K fashion, and gorpcore have quickly gained traction among niche communities before expanding to larger audiences. Fueled by TikTok trends, micro trends can often disappear as fast as they emerge, making them difficult to track through traditional methods.

The Evolution of Fashion Trend Forecasting

Fashion trend forecasting has evolved from a largely manual process, reliant on industry experts, to a tech-powered endeavor. Historically, trend forecasters would attend fashion shows, study cultural movements, and rely on their intuition to make predictions. This approach, while valuable, often failed to account for the sheer volume of real-time data that modern forecasters need to sift through—especially with the explosion of TikTok trends and influencer-driven micro trends.

Today, companies like Heuritech offer AI-driven solutions, scanning digital landscapes for emerging trends. Trendee takes this even further by utilizing a multimodal LLM that not only analyzes text but also interprets images, videos, and consumer sentiment from social media, retail, and runway channels, allowing for a holistic understanding of what’s trending.

Why Fashion Trend Forecasting is Challenging

Forecasting fashion trends has always been difficult, but the modern fashion ecosystem presents even more challenges:

• Data Overload: With millions of social media posts, TikTok videos, and e-commerce activities occurring daily, fashion forecasters are inundated with data. Sorting through this flood of unstructured information is nearly impossible without advanced AI solutions.
• Trend Volatility: Micro trends, often born from viral TikTok moments or influencer endorsements, can rise and fall within weeks. This volatility makes it tough for brands to keep up, let alone plan collections around fast-changing preferences.
• Global Variation: Fashion trends can vary significantly across different regions and cultures, making it hard to create universally relevant forecasts. A style trending in New York might not resonate in Tokyo, for instance.

Why Generative AI is Crucial for Fashion Trend Forecasting

Generative AI is revolutionizing fashion trend forecasting by solving many of the industry's current challenges. Here’s how:

1. Real-Time Analysis of Unstructured Data: Traditional forecasting methods often rely on reports compiled by fashion experts, which can lag behind real-time events. Generative AI can process and analyze vast amounts of unstructured data, such as social media posts and TikTok videos, in real time. It identifies emerging TikTok trends, visual patterns, and consumer sentiment far more quickly than human analysts.

2. Faster Response to Fashion Trends: Generative AI does more than just identify fashion trends; it also powers AI fashion design generators that create new designs based on those trends. By analyzing what influencers and consumers are wearing, AI can propose fresh styles or refine existing designs to align with emerging preferences. This enables brands to respond swiftly, significantly shortening the time between trend discovery and product creation.

1. Improving Trend Narratives: Beyond identifying what is trending, generative AI helps brands understand why a trend is happening. By examining the broader cultural and social forces at play, AI can generate insights into how and why certain styles are resonating with consumers. This ability to craft a narrative around the evolution of a trend can lead to more compelling, brand-aligned collections.

How Trendee Differentiates Itself with Multimodal LLM

While companies like WGSN and Heuritech offer strong AI-based solutions, Trendee's multimodal LLM approach goes a step further. By combining the analysis of text, images, and video data, Trendee is able to identify trends across multiple channels with high accuracy. For example, Trendee can automatically recognize not just what’s trending in fashion photos on Instagram but also the underlying color palettes, fabrics, and styles that are gaining popularity.

This multimodal capability is particularly important in an era where TikTok trends and influencer marketing have significant impact on fashion. It allows Trendee to forecast trends more accurately by analyzing not only what influencers are wearing but how these outfits are being received by their followers—capturing real-time shifts in sentiment that can drive purchasing decisions.

Challenges and Limitations of Generative AI in Fashion Trend Forecasting

While generative AI holds tremendous promise in transforming fashion trend forecasting, there are several challenges and limitations to be aware of:

1. Generic LLM Models Are Not Fashion-Specific: Most large language models (LLMs) like GPT are not trained specifically on fashion data, which makes them less effective in identifying fashion trends accurately. While these models may excel at recognizing basic elements such as colors, fabrics, and product details, they struggle to identify nuanced styles and trends that are deeply rooted in specific lifestyles, aesthetics, and subcultures. For example, a generic LLM might recognize an image containing "wide-leg pants," but fail to understand that they are part of a larger retro or minimalist Fashion styles are highly subjective and interconnected with cultural movements, making it difficult for non-specialized AI models to capture these subtleties.

Trendee’s multimodal LLM addresses this issue by being trained on fashion-specific data from diverse sources such as runways, social media, retail, and influencer content, allowing it to recognize and forecast trends more accurately. It can detect both the style and cultural context behind the trends, offering a more refined understanding than generic LLMs.

2. Identifying Niche Trends at Scale is Challenging: One of the biggest hurdles in fashion trend forecasting is identifying and scaling niche trends. Micro trends often originate from small, specific communities before spreading to the mainstream. Trends like mermaidcore or balletcore, for instance, may initially be popular within subcultures, making them hard to detect with traditional AI models that focus on larger datasets. Additionally, niche trends can be fleeting, emerging quickly on platforms like TikTok and disappearing just as fast. Generative AI models need to be constantly updated with real-time data to effectively capture and track these niche trends.

3. AI-Generated Designs May Be Too Artistic or Impractical for Manufacturing: While generative AI can create innovative fashion designs by analyzing trends and suggesting new styles, these designs may sometimes be too abstract or artistic for practical manufacturing. AI lacks the human understanding of practical constraints such as fabric properties, construction techniques, and cost-efficiency. As a result, some AI-generated designs may look impressive but be difficult, if not impossible, to produce at scale.

Rather than replacing human designers, AI-generated designs should be seen as a tool to enhance creativity, offering new ideas and inspirations that can be refined by human expertise. Human designers bring cultural sensitivity, craftsmanship, and an understanding of consumer desires, ensuring that AI-assisted designs remain both innovative and feasible for production.

Conclusion

Generative AI is revolutionizing fashion trend forecasting, offering faster and more accurate insights into what’s trending across platforms like Instagram and TikTok. Companies like WGSN, Heuritech, and Trendee are at the forefront of this transformation. Trendee's multimodal LLM approach differentiates itself by providing a holistic view of fashion trends, integrating text, image, and video analysis to capture trends in real time.

However, the journey is not without challenges. Generic LLM models, while useful for recognizing basic elements like colors and fabrics, struggle to accurately identify fashion styles tied to specific lifestyles and aesthetics. Trendee’s fashion-domain multimodal LLM overcomes this by analyzing fashion-specific data to grasp the cultural and emotional nuances behind trends.

Another challenge is identifying niche trends at scale. Micro trends often emerge from small, specific communities, making them hard to detect without constantly updated real-time data. This highlights the need for models that are capable of both large-scale and granular analysis.

Moreover, while AI can generate innovative designs, these creations can sometimes be too artistic or impractical for manufacturing. AI is a powerful tool to facilitate creativity, but it cannot replace the craftsmanship, cultural insight, and practical knowledge that human designers bring to fashion.

In sum, generative AI holds immense potential for fashion trend forecasting, but it must be paired with specialized, fashion-focused models and human expertise to navigate the complexities of style, culture, and practical application. By addressing these limitations, companies like Trendee are leading the charge toward a more data-driven, efficient, and responsive fashion industry.
