The United States has the largest apparel market in the world. As apparel dollars continue to shift from brick-and-mortar stores to online channels, the outlook for physical retailers is grim. The apparel industry has seen its share of the total digital spend grow over the past three years, from 15.4% in 2013 to 17% in 2016. Nevertheless, purchasing fashion and apparel items online can still be complicated: take for instance someone who orders their prom dress from China; what they think they are buying vs. what they receive is often unmatched. As e-commerce transactions progressively become the norm, online retailers must respond to growing consumer demands for seamless, reliable shopping methods and, unsurprisingly, Amazon is leading the way.

Amazon has serious designs on capturing the fashion and apparel market. The company has been ramping up its investment in the sector, with initiatives such as the development of its own private-label clothing brands, and most recently the introduction of Amazon Prime Wardrobe. Currently in beta mode, the

service will let shoppers try on clothes and return them for free, an initiative designed to seduce more brands into Amazon’s marketplace.

Let’s take a closer look at Amazon’s place in the U.S. apparel market and identify some emerging trends:

The Numbers

  • 25%: The YoY growth of’s Apparel sales.Of the top performing Apparel categories on Amazon for 2016, three involve men’s clothing. A traditionally female-driven activity, online apparel shopping is luring a new male demographic. It’s easy to see how Amazon’s hassle-free shopping efforts would attract men who avoid stepping into a clothing store (instead relying on their wives or mothers for new underwear). We see a similar trend with the popularity of Women’s Intimate Apparel: women (and gift-buying men) who feel awkward buying lingerie at brick-and-mortar retailers are now going online instead. Top Performing Apparel Categories, 2016

Men's Bottoms$375
Women's Intimate Apparel$250
Women’s Denim$170
Men’s Underwear$165
Men’s Workwear$225

Our data suggests a trend in Apparel where companies and categories dominate by having a large number of items with lower levels of sales as opposed to having high-selling items. This is illustrated with men’s underwear and socks which make up many of the top selling items, but are rarely if ever in the top 5 categories, while the top selling categories include none of the top items. Hanes, for example, has incredibly high sales in the Men’s Underwear product group, holding 3% market share in 2015, which has already grown to 5% market share today.

Apparel and footwear sales have seen a relatively slow growth rate since the economic crisis in 2008, with an increase of only 3.8% worldwide, bringing the total value to $1.67 trillion. Formalwear has also been in decline. As the population shifts away from restrictive dress codes towards a more casual lifestyle

(considering the increased flexibility of working from home for example), the need for formal work attire is gradually diminishing.

Consumers are increasingly opting to wear sports apparel and athletic footwear for numerous daily activities, from working out at the gym, to running errands and working from home. The sportswear category (items such as yoga pants and activewear) has the highest year-over-year global sales growth with an increase of just under 7% in 2016, outpacing all other categories for the third year in a row.

Looking at Amazon’s ‘Top 5 Growth Apparel Categories’, we notice that this casualization of dress norms, known as the athleisure trend, is apparent. Comfort and athleticism are becoming the major influencers behind today’s apparel design. And as we explored in our analysis of Outdoor & Sporting Goods, athletic apparel is a product sector that is experiencing great success in e-commerce, with a disproportionately high share of consumers choosing Amazon over brick-and-mortar stores.

In both the US and UK, the men’s underwear category is performing highly on Amazon, however, Americans clearly prefer Hanes whereas Calvin Klein is the undisputed favorite in the UK. For the past 25 years, Calvin Klein’s signature logoed underwear have been popular among men and women due to its combination of timeless black and white advertising with monochromic designs and of course, good quality cotton. Recently, however, the brand’s smart social media campaigns have catapulted its underwear collection into a new realm of prominence (which can be seen in our data). The original #MyCalvins campaign endorsed celebrities, models and bloggers with the classic Calvin Klein logo underwear and encouraged recipients to post half naked photos of themselves in the garment on Instagram. Naturally, the public quickly followed suit, posting their own #MyCalvins photos, and the rest is history.

Amazon still struggles in the luxury brands category since many refuse to sell on Amazon due to the platform’s lax knock-off policies. Despite this, our data shows that the company is having great success with necessities and everyday items such as jeans, socks, underwear and men’s work clothes. In their efforts toward a hassle-free shopping experience, Amazon is investing in innovation: in payments, order fulfillment, product selection and now, with Amazon Prime Wardrobe, return policy flexibility. For these reasons, Amazon continues to gain loyalty among digital consumers, and One Click Retail will be closely monitoring any and all future developments with Amazon in the apparel market, eager to see how digital shoppers respond to these initiatives and when the next market transformation will occur.
