Fashion Advertising Agency

The mind of a fashion consumer

Fashion decisions are emotional, expressive, and instant. From discovering a look on Instagram to spotting it on a city billboard, consumers act in moments of inspiration. Winning their attention means showing up with creative that feels current, desirable, and true to your brand identity.

We use data-led insights to segment audiences by style, mindset, and moment, not just by age or gender. We identify fashion tribes, seasonal purchase cycles, and content touchpoints that influence discovery and intent. This lets us craft campaigns that drive not only clicks and conversions but long-term brand affinity.

From elevating household fashion names to helping emerging designers cut through, our consumer-first planning ensures your brand isn’t just seen, it’s wanted.

Fashion Retail & Shopper Marketing

In fashion, the sale is often won or lost in the moments between inspiration and purchase. That’s why we connect brand storytelling with retail and eCommerce environments to influence shoppers at every step of their journey - from Tiktok discovery to billboard advertising. 

Our approach combines in-store activations, window takeovers, digital screens in shopping districts, and online retail media to create seamless, high-impact campaigns. From launch moments to seasonal drops, we design visibility that converts attention into sales both online and offline.

We also help brands strengthen relationships with retail partners, align with merchandising calendars, and optimise performance around peak trading periods. By linking creative storytelling to commercial outcomes, we turn brand presence into lasting demand.

The Fashion Advertising mix

It’s impossible to define the ‘right’ advertising model for a fashion producer or brand, because a lot will depend on where the company is currently positioned in this rapidly moving market, and the objectives it wants to achieve. Some of the many aspects of fashion advertising we can assist with include:

  • Outdoor ad campaigns, with billboards and digital screens in major city centres, luxury shopping and entertainment complexes, and timed to coincide with big events in the fashion world like London Fashion Week.

  • Print and editorial promotions, partnering with fashion or lifestyle magazines to achieve positive associations and ensure trend-focused audiences have familiarity and awareness of the brand.

  • Social media advertising, whether based on targeted age groups and platforms or on partnerships with influencers, public figures, and stylists whose audiences trust and whose style or image they want to emulate.

  • Digital video promotions, using short-form video content and interactive features like lookbooks to extend brand reach across channels like YouTube, alongside within search, AI citations and social media. 

Fashion businesses can also look at blending any or all of these formats with in-store activations and online experiences, from giveaways to runway shows, competitions and first-look exclusives.

Types of Fashion Sector Ads

Who Is Fashion Advertising For?

We’re all familiar with glossy ads in magazines, and with huge billboards in every major capital city. However, fashion advertising isn't just for luxe and well-known brands, and is vital for any company that needs to build an identity and create an impression. 

One Day works with:

  • Established fashion companies that either need to retain their visibility or improve relevance with changing trends or new consumer groups.

  • New labels and design brands that rely on advertising to launch new collections, and to ensure they continue to develop better awareness.

  • Retailers and online ecommerce brands, which encourage higher visitor numbers to their sites or marketplaces and improve interest in sales events through digital advertising campaigns.

  • Lifestyle and other brands associated with the fashion sector, such as those producing sunglasses, jewellery or shoes. These companies design campaigns that align them with fashion culture and trends.

As we mentioned above, many modern consumers prioritise ethics and sustainability. Across all these types of companies, we see a large proportion of businesses that use advertising to share their values and ensure they're seen as purpose-driven.

Frequently Asked Questions.

    • Ads for fashion brands extend beyond incentivising sales. They create moods, trends, messaging, and lifestyle connotations that audiences want to be part of.

    • Businesses use carefully crafted storytelling that incentivises consumer responses based on age, interests, style, and current trends, such as street-style collaborations and partnerships.

    • Precision targeting minimises wasted resources, giving companies in-depth data they can use to reach defined consumers, via both offline and online ad formats.

    • The cyclical nature of fashion, with seasonal ranges, ensures brands can align their promotions with the products and colours consumers are actively looking to buy at the time each campaign is launched.

    • Effective fashion advertising embraces the brand's persona and emphasises key USPs, such as sustainability, cultural relevance, and ethical production standards that consumers want to see.

  • The fashion industry is often seen as fun and exciting, but to compete, brands need to be tactical with their campaign messaging and ensure they're fully aware of the strict regulations and consumer expectations their ads must comply with. Expert marketing advisers can help with:

    • Improvements in brand recall and recognition, using campaigns that are consistent across multiple platforms, with standout designs that consumers will remember.

    • Adherence to the Advertising Standards Authority (ASA) regulations, which set rules on stereotyping, representation, diversity, and pricing transparency.

    • Delivering ad campaigns that are aspirational and emotional and have a direct impact on click-through rates and sales, supporting either overall brand awareness projects or launches of new seasonal ranges.

    Importantly, well-designed fashion campaigns can deliver long-term value by building loyal audiences invested in a brand's success, especially for newer start-ups with novel concepts or production techniques that align with cultural values.
