Analyst · Cowen and Company
Thank you, Chris, and good morning, everyone. Today, I will provide a brief overview of our first quarter performance as well as give you an update on our progress with the key strategic initiatives planned for 2015. Stuart will then walk you through our financials and guidance in more detail.
We delivered strong results in our first quarter despite headwinds from weather, port-related delays and foreign exchange impact. Specifically, we delivered first quarter revenues above the high end of our guidance, generating overall comparable sales growth of 6%, driven in part by a 31% increase in our e-commerce channel.
Within our North American business, we saw another quarter of positive combined comps and a nice acceleration in our e-commerce business in both the U.S. and Canada. Our women's business once again delivered positive comps in the quarter, driven by our bottoms category. Our guests responded well to our assortment in the quarter, despite the impact of product flows coming out of the port disruption. We have seen an acceleration in our business in the latter part of the quarter as our inventory positions began to improve, validating our new product flow and assortment.
Additionally, we saw further ramp in our men's business, delivering a 19% comp, and finally, ivivva delivered a 29% comp on a combined basis. We achieved this growth across our key categories despite the challenges related to the West Coast port disruptions. We look forward to seeing how our guests respond in Q2 and through the second half of the year when our product assortments are properly balanced by season and in quantity.
We ended the first quarter with elevated inventory level as a result of the port-related delays. However, we are finally reaching better in-stock positions and are confident in our plans to work through this inventory with no impact on brand equity and minimal markdown risk. Stuart will provide additional color on this during his remarks.
Before getting into further details on the quarter, I would like to pause and offer my sincere gratitude to Delaney Schweitzer, who left lululemon at the end of last month after 13 years with our collective. Under her leadership, Delaney developed incredible leaders, and as a result, we have a deep bench of talent poised to lead our global retail business. We are empowering these leaders to oversee the Americas, Asia Pacific and Europe.
Collectively, our retail leadership team brings history, experience, passion and commitment to our culture. Their energy will inspire our people and fuel our growth.
Our expansion into international markets continue to be a key growth driver. In Asia, we opened our second store in Singapore at Takashimaya shopping center on May 13 and have already seen fantastic results well ahead of our expectations. Additionally, our initial store in Ion mall continues to outperform our plan, and we are eagerly anticipating the opening of our first Hong Kong store at ifc mall, which we expect to be amongst our most productive stores across our global portfolio. We also have plans to open a second store in Hong Kong in Q3 in Hysan Place located in the heart of Causeway Bay. Last but not least, we are on track to open our first store in Dubai in Q3 of this year.
On our last call, I outlined both our short- and long-term goals as a growth company, building a global iconic brand across geographies and new categories, and we continue to make strategic investments in the key elements of our brand operating model: one, our product; two, our guest experience; and three, our brand and community. Beginning with product, we continue to see the benefits of the ongoing work on our product engine connected within Tara's group. Our design ecosystem is leveraging our culture of innovation, and we are achieving this by expanding our design organization and through our relentless focus on functional innovation.
A key component of this process is the deep relationship and feedback loop we have built with our ambassador [ph] community. Our ambassadors are real-life inspirational leaders in their communities who live the sweat life to its full extent, 365 days a year. They are an integral part of the product development process. Our ambassadors sweat in our product then give us valuable feedback to assist our whitespace R&D group. They truly love being a part of our early product design cycle, and we are always looking at new ways to deepen this aspect of our relationship with them.
Turning to some specific product highlights from the last quarter. We saw continued momentum in our women's pants business. Our earlier work to reinvigorate this key category continues to pay off. As an example, our wunder under franchise is performing extremely well, especially with the addition of new styles over last year. These strong positive signals bode very well for the relaunch of our pant wall expected [ph] in Q3.
And our tank line is evolving as well with the introduction of higher-support construction, more diverse coverage options and a wider selection of fits. This initial new offerings are hitting our stores in late Q2 and into Q3, and we look forward to creating the same level of excitement and energy with our tanks as we did with our bottoms. These efforts will continue to inform the full relaunch of the tank wall in the first half of 2016.
We are thrilled to see the accelerated momentum in the men's business as evidenced by its 19% comp, and we have expanded option within popular categories, including our Metal Vent tech T-shirts, which further reinforced the strong growth of our foundational sweat business. We are also experimenting with different store formats and shopping experiences aimed at our male guests. The Joinery, currently found in our men's SoHo store in New York and Robson store in Vancouver, allows a personalized experience where guys can customize the function of their shorts on the spot. The concept of The Joinery is firmly rooted in a function-first approach, letting men craft their own workout gear.
Creating an authentic best-in-class guest experience is the second key area of investment. We continued to strengthen our omni-channel capabilities with projects targeting improvement both in-store and online. For example, our website is undergoing a full global redesign to ensure we have a scalable transactional platform that will allow us to showcase a broader assortment of product online, better enable product storytelling and deepen our product education capabilities. Some key features will include enhancement to the checkout process and targeted recommendations, while ensuring the site is optimized across any device. Phase 1 will launch in the latter part of this year and prior to holidays.
The final key area of investment for this year is within our brand community efforts. We continue to see the highest engagement with our guests when we powerfully tell our product stories in a way that is locally relevant for them. As I mentioned earlier, we recognize and embrace the power of our ambassador community, and this past quarter, we hosted 130 of them from around the world at our annual ambassador summit in Whistler, British Columbia. Our goal for this year's summit was to intentionally deepen the integration between our local educators, our support center team, whitespace and our global ambassador community.
And just last week, just last Friday actually, in Vancouver, we kicked off a 16-city global tour, where we will connect with many facets of our collective, including our educators, store support teams and ambassadors. Our educators absolutely never cease to amaze me. They are the best at what they do and hold the most important job within the company. They create authentic connections with our guests by listening to their passions, understanding their needs and how they like to sweat, and most importantly, encouraging them in studying, pursuing and celebrating their goals. This, too, is one way to express our gratitude and connect with thousands of our educators and ambassadors around the globe. Our brand lives within our people, and during the tour, we will reaffirm our mission and create our future together.
In conclusion, lululemon is a powerful and unique brand, and our core values will continue to guide our future. Our business model gives us full control of the experiences we are creating, and we are relentless in our pursuit of innovation in everything that we do, resulting in unparalleled guest loyalty. We have made the shift from playing defense to playing offense, and we have set a course of sustainable and profitable growth both within North America and in our global market.
Before turning the call over to Stuart, I would like to express my gratitude to the entire lululemon collective who makes up our iconic brand. It is our combined passion and commitment that will allow us to capitalize on the many opportunities that lie ahead.
I'll now turn things over to Stuart for a more thorough review of our financial results and guidance. Stuart?
