Amazon's Ascendancy in the Apparel Market

Amazon has firmly established itself as the premier destination for clothing in the United States, a position significantly bolstered by the surge in e-commerce spending during the pandemic in 2020. This growth solidified Amazon's status as the top apparel retailer, overtaking Walmart, which held the position until 2018. The trend has proven to be more than a temporary pandemic effect, with the segment continuing its expansion. In 2020, Amazon accounted for nearly 13% of all US clothing sales, with its apparel and footwear sales more than doubling Walmart's and exceeding ten times the online clothing business of its closest competitor.

Despite its market dominance, Amazon presents a costly platform for apparel sellers, characterized by rampant returns and high fees. Nevertheless, its unparalleled global reach makes it an indispensable channel for both large brands and small businesses, fostering a reliance that is difficult to overcome once established.

Amazon's Strategic Expansion into Apparel

Amazon's journey into the apparel space, which began in earnest just over a decade ago, is a testament to its ability to leverage its existing scale and dominance in e-commerce. Starting as a bookseller, Amazon systematically expanded into new categories, including toys, electronics, and eventually apparel.

Early Initiatives and Data Utilization (2012-2014)

First Advertising Campaign (2012): Amazon Fashion launched its inaugural advertisement campaign, actively seeking partnerships with brands like Vivienne Westwood and Kate Spade.
Personalized Recommendations: The company began employing customer data to tailor search recommendations, enhancing the user experience.
Talent Acquisition: A concerted effort was made to hire models and stylists to improve the presentation of its apparel offerings.
Sales Growth (2014): By 2014, Amazon's apparel and footwear segment was estimated to have generated approximately $7 billion in sales.

Private Label Expansion and Challenges

Within a few years, Amazon significantly ramped up its private label initiatives, introducing dozens of in-house brands and tens of thousands of products. By 2022, over 100 confirmed private label brands were in operation. However, some of these ventures have since been discontinued to cut costs, with reports suggesting that private label operations were not consistently profitable. Brands like "Amazon Essentials" and "Amazon Basics" have found success by focusing on frequently ordered, less experimental items. Amazon's strategy appears to favor selling a high volume of a limited number of items rather than a wide variety of unique products, a challenge given the seasonal and trend-driven nature of apparel.

Brand Engagement and Market Dynamics

Major players have been expanding their presence on Amazon for years by establishing dedicated storefronts. This trend continues, with companies like Michael Kors and David's Bridal launching storefronts in 2025. Notably, Nike has returned to the platform after a 2019 exit, which was driven by concerns over brand control and a push for direct-to-consumer sales. A significant factor in Nike's return, and that of other brands, is the worry about unauthorized sellers listing their products on Amazon. Even if a brand withdraws, it cannot fully control third-party listings. This was particularly evident during Amazon's early growth phase, prompting brands like North Face to seek to clean up unauthorized distribution. At that time, Amazon's apparel segment was experiencing a 40% compounded annual growth rate.

Luxury Storefront Initiative

More recently, Amazon has focused on its Luxury Storefront, launched in 2020. In April 2025, a partnership with Saks Fifth Avenue enabled the sale of products from high-end brands such as Dolce and Gabbana and Balmain. Amazon has been actively approaching luxury brands, with dedicated teams reaching out to founders and CEOs to encourage them to join the platform.

Amazon, in a statement to CNBC, expressed pride in partnering with a diverse range of selling partners and brands, from small businesses to global names, and committed to continued investment in tools and services to help brands grow.

Seller Models on Amazon Marketplace

There are two primary ways for sellers to participate in the Amazon Marketplace:

Amazon Purchases Inventory: Amazon buys products in bulk from a company and then controls pricing and listings. This model, which previously constituted a larger portion of the marketplace, is now by invitation only. According to Hawke Media, brands typically need to generate at least $10 million in annual sales on the platform to be considered, though Amazon disputes this figure. This model allows Amazon to avoid tying up capital in inventory, shifting that responsibility to the brands.
Third-Party Seller Fees: The more common method involves sellers paying Amazon a fee to list and sell their products. For apparel, these fees typically range from 5% to 17%, depending on the item's cost. However, the FTC lawsuit in 2023 alleged that sellers could pay up to 50% of their revenues to Amazon when all costs are considered. Amazon has denied these allegations, stating a lack of sufficient knowledge to form a belief as to their truth.

The Allure of Amazon for Sellers

Despite the high fees, the primary draw for sellers is Amazon's access to an enormous consumer base that they would otherwise struggle to reach. This leads to high order volumes, which Amazon facilitates through Fulfillment by Amazon (FBA).

Fulfillment by Amazon (FBA)

FBA is an optional service where Amazon handles processing, shipping, and returns for an additional fee. This service can incur various costs, including monthly subscription fees, long-term storage fees, removal order fees, return processing fees, and unplanned service fees. For new online businesses, FBA acts as a significant "jumpstart," offering services that most small businesses cannot manage independently. This model has inspired competitors like Walmart to launch their own fulfillment services.

Allegations of Data Misuse and Anti-competitive Practices

A Wall Street Journal investigation revealed that Amazon has allegedly used third-party seller data to create "dupes" or replicas of successful items under its own brands. An example cited involved Peak Design, a camera bag manufacturer, whose popular product was allegedly copied by Amazon. While Amazon eventually removed the infringing product after a public demonstration, many small businesses lack the resources to pursue such actions and may be undercut by Amazon's similar offerings.

Amazon stated to CNBC that it does not use non-public data from individual sellers to determine private brand product launches and has robust policies to protect seller data.

Pricing and the Buy Box

The FTC lawsuit also accused Amazon of anti-competitive pricing practices, alleging that sellers are penalized if they offer lower prices outside of Amazon's marketplace. CNBC observed instances where major brands' products were cheaper on Amazon than on the brands' own websites. Amazon monitors prices using Universal Product Codes (UPCs), which are unique identifiers for products across retailers.

To circumvent potential price matching issues, sellers are advised to use UPCs specific to Amazon. When Amazon detects a seller offering lower prices elsewhere, sellers receive an alert and are required to adjust their pricing. Failure to comply can lead to penalties, including disqualification from the "buy box." The buy box, where shoppers click "Add to Cart," accounts for 98% of all purchases, making it critical for sales volume.

Amazon maintains that other retailers use similar tools to highlight competitive offers and provide customer value, stating they do not promote non-competitively priced offers. While facing legal scrutiny, Amazon's ability to command low prices has been a key driver of its success.

The Challenge of Returns in Apparel

One of Amazon's primary appeals is its easy return process, especially for Prime products. This, combined with competitive pricing, has fueled its market share. However, sellers report significantly higher return rates on Amazon compared to other platforms, forcing them to increase prices to offset lost margins and fees.

The apparel category is particularly susceptible to high returns. Consumers may order multiple sizes or colors to try on at home, leading to costly reverse logistics for Amazon and sellers. In many cases, sellers incur losses on returned items, sometimes negating any profit from the initial sale.

Environmental Impact of Returns

A significant issue uncovered is that the vast majority of returned apparel, both on Amazon and elsewhere, does not re-enter the seller ecosystem. Instead, these items are often sent to landfills or incinerated, contributing to billions of pounds of waste annually. In 2022, Amazon confirmed to CNBC that it uses "energy recovery" (incineration for energy production) as a last resort.

Experts note that returns are exacerbated in categories like formalwear or Halloween costumes, where items may be returned after being worn. The high volume of returns is identified as a major detriment to online fashion businesses, though some argue the trade-off is worth it for customer acquisition and sales volume.

Discontinuation of "Try Before You Buy"

In early 2025, Amazon discontinued its "Try Before You Buy" program, launched in 2018. This service allowed customers to try select apparel, shoes, and accessories before purchasing and, crucially, exempted sellers from fulfillment and processing fees for returned items. The discontinuation suggests that even Amazon found the program's associated losses unsustainable, highlighting the immense difficulty of managing returns in the apparel space for smaller businesses.

Amazon's Experimentation and Advertising Prowess

Amazon is known for its rapid experimentation, even with initiatives that may not succeed. The company's exploration into a vertical video offering called "Amazon Inspire" did not pan out, but it did yield valuable insights into the effectiveness of digital advertising. A report indicated Amazon as the top brand on TikTok by earned media value, generating an estimated $1 billion in advertising value through unpaid organic exposure. While not apparel-specific, social media platforms like TikTok are well-suited for the fashion segment.

Evolving Brand Sentiment Towards Amazon

The perception of brands selling on Amazon has shifted dramatically. In the early years (2012-2015), it was seen as a "greenfield" opportunity, offering immense freedom. By 2023-2024, Amazon has become a necessity, a platform brands feel compelled to use due to its vast customer base, even if they don't actively desire it. This presence is crucial for showcasing products, engaging with customers, and reporting to investors.

The emergence of platforms like TikTok Shop is seen as a complementary force, attracting attention, while Amazon serves as the platform that captures and converts these customers.

Future Outlook for Amazon Apparel

Wells Fargo estimates that Amazon's apparel and footwear segment will grow by another 7.5% in 2025, exceeding $70 billion. The debate for brands is no longer about whether to be on Amazon, but how to best work with the platform.
