49% of online shoppers feel positively about having their own AI personal shopping assistant that is able to find fashion items based on their preferences such as budget or size.
Technology is developing rapidly and there are opportunities for the latest sizing tools from AI-powered virtual fitting rooms to 3D avatars to address help customers find the correct size and fit when online shopping. However, getting consumers to become accustomed to using the tools during their shopping journey is crucial and this will depend on how accurate customers find them and if the items actually fit when they physically try them on, leading to reduced returns.
Shein has become the most popular place for young women aged 16-34 to buy new fashion items online. The Chinese etailer has achieved incredible scale in a relatively short period of time, grabbing market share from other pureplays as well as young fashion retailers. This has been fuelled by its distinctive business model that combines fast fashion principles with AI-powered decision-making, global supply chain agility, and aggressive digital marketing to respond with speed and ultra-low prices to the latest fashion trends.
The latest technology is transforming the way consumers shop, so retailers must invest in innovative solutions to address consumer pain points and stay competitive.

What goes into a Mintel Market Intelligence Report?
Curious about how a Market Intelligence report comes together? We like to think of it as building a detailed puzzle. We start with individual pieces: data from consumers, market statistics, industry trends, and online conversations. Then our expert analysts add world-class human insight and industry knowledge. The pieces are assembled to reveal a clear, comprehensive picture of a market.
The Four Pillars of Our Research
We use a combination of four main research methods when creating our reports, each adding a valuable perspective:
- Consumer Research: Direct surveys with real people, giving us clear, current insights into what people think and do.
- Desk Research: In-depth review of trusted data sources. We use this rich database, plus powerful internal tools that track new products and market sizes, to detect trends and guide forecasts.
- Trade Research: Insights from conversations with industry experts. Their real-world experience helps us understand what’s happening behind the scenes.
- Brand and Social Media Research: Analysis of online opinions and trends. This lets us spot trends, measure brand sentiment, and capture feedback in real time, adding further depth to our research.

Bringing It All Together
Each of these four pillars provides a different piece of the puzzle. Consumer research tells us what customers think, desk research provides the factual framework, trade research offers an insider’s view, and social media analysis reveals public sentiment.
Our expert analysts are skilled in weaving these diverse data streams together. They apply a range of quantitative and qualitative analysis techniques to uncover the deeper story, connecting the dots to deliver clear, actionable insights. This comprehensive, multi-layered process is how we transform raw data into a market intelligence report you can trust to inform your most important business decisions.
