Thanks, Calvin. Let me also welcome you to lululemon. We're really excited to have you join the team and look forward to working with you on our next phase of growth.
Our second quarter results mark another important step in the journey toward our 2020 goals as well as the continuation of the top line inflection that began last year and we now see extending into Q3, which is reflected in our sales outlook for the quarter.
In fact, we're now tracking to meet or even exceed a $4 billion revenue goal with men's and e-commerce effectively ahead of schedule. Our product assortments and supply chain work continue to exceed expectations, contributing to our gross margin that is now firmly reaching the mid-50s range. This result, combined with our solid SG&A management, has produced a trailing 12-month EBIT margin of nearly 21%, delivering on our goal of a low 20s operating profit. And it's important for our investors to understand that we still see opportunity for margin expansion as we further invest in these already successful initiatives, including expanding our e-commerce business, segmenting our supply chain, reducing lead times and expanding our distribution network. We believe our margins can continue to expand into the future.
Turning to the headlines for Q2. We saw a broad-based acceleration in our business across an array of categories, channels and geographies. We had said on the Q1 call that our great results in that period were not simply a case of lapping weak prior year comparisons, and our Q2 results continued the story, reflecting the success of our ongoing structural investments.
Combined comps for the quarter increased 19% on top of a 7% increase last year. This top line growth, along with significant improvements in gross margin and SG&A, delivered an 82% increase in EPS for the quarter. By channel, we saw store comps increase 10% and digital was up 47% versus a strong prior year comparison.
This continued strength in our comps reflects the success we are seeing in our guest acquisition that increased 30% in the quarter and is fueling traffic increases across all channels. Specifically in stores, we saw a high single-digit lift in traffic while traffic to our e-commerce site grew over 20%. Improved product assortments and better brand and community building efforts, including several successful activations, also contributed to these strong traffic trends.
We're also particularly pleased with the ongoing strength in e-commerce, which posted double-digit conversion and [ AOV ] increases in Q2 as our digital business continues to benefit from last year's site relaunch in Q3. Our guest is responding well to the improved experience, and we still see opportunities to remove friction and increase efficiency on the site as we continue to improve the search and checkout functions as well as expand further into personalization.
Our product assortments also performed well across practically every category in Q2, with double-digit increases across women's, men's and accessories. Women's pants, which is our highest margin category, along with men's pants, both posted comps over 30%. And women's tops generated another healthy double-digit increase as we gain traction in this category. It's also exciting to see accessories delivering its strongest quarterly comps in the last 5 years at over 20%.
And Q2 saw several successful brand activations. An important moment for all of us here at lululemon was how we celebrated International Day of Yoga. Stores in more than 50 cities around the world hosted successful yoga classes on June 21 and we donated over $1 million through our Here to Be social impact program. We are incredibly proud of Here to Be, which benefits nonprofit groups that increase access to yoga and meditation for communities that face barriers to wellbeing. We continue to invest in this program to effect positive change in the communities around the globe where we work and live.
Turning now to our growth pillars. I'd like to offer some details on our strategic priorities, which continue to be extending our success in our digital channels, ramping our international expansion with a near-term focus on Asia, innovating our product assortments with a focus on accelerating growth in men's and continuing to roll out stores in North America that build on our important store format innovations.
Our teams continue to deliver great results across these areas, which is setting the stage for our next chapters of growth. I'll share some highlights on our progress within each of these pillars now.
In digital, it's exciting to see our momentum continuing to build. Excluding the warehouse sale from last year's results, the constant dollar comp was 65% for Q2. And as I mentioned, traffic and conversion continue to be strong as both new and existing guests are responding well to enhanced online experience. Over the last 12 months, we've doubled the number of guests with whom we can communicate, and in Q2, we saw 80% growth in our e-mail file.
We continue to see significant opportunities to enhance our digital guest experience. You've heard us talk about improvements we're making this year in checkout, search and personalization. Let me offer a couple of updates here.
In checkout, in Q2, we saw a significant increase in the percentage of guests completing the checkout process, reflecting ongoing tactical improvements to the site. And in personalization, we now have our initial data scientist teams embedded within our brand teams who helped deliver insights used to inform and drive our successful Father's Day campaign. We are making steady progress here and expect to see ongoing improvements over the next several quarters.
Turning to our international business. Our combined comps in Asia increased 50% this quarter as we continue to build momentum in the region. And importantly, in China, our e-commerce business continues to lead the way with a comp increase of over 200%. We lost our WeChat store in China in Q2 and remain on track to launch e-commerce sites in Korea and Japan later this year.
In Europe, comps were again better than planned, an increase in the strong double digits. While we still have much work to do in this region, we're excited to see that our brand is resonating. We opened our first store in Sweden in a key destination city, in Stockholm. And in London this quarter, we hosted another successful Sweatlife Festival in which we partnered with 13 studios to offer over 250 classes and attracted over 4,500 guests.
Within product, we lead with innovation and continue to find success in our core classifications as we leverage our key franchises, including a line for women and ABC for men. Guests are also responding well to our newer office travel commute styles, including the on-the-fly collection, which offers versatile and "away from the body" silhouettes.
Our men's business continues to accelerate, reaching a total penetration of 22% in the quarter with great new styles planned for the second half. And looking forward to fall, we're really excited for the expansion of our outerwear business. Despite the heat in August, we're already getting great initial reads on our early jacket and outerwear offerings.
And our North American stores continue to post impressive results with store traffic accelerating sequentially for the past 5 quarters and now extending into the early part of Q3. We opened 4 net new stores and completed 7 co-located remodels in Q2. We expect to open approximately 40 new locations in total by year end. In addition, we're seeing great success with our seasonal store strategy with 23 opened at the end of Q2 and plans to more than double that number into Q4.
We also remain on track with our "buy online, pick up in store" initiative, which will begin to roll out later this year. Combined with the ship from store and our [ BBR or endless aisle ] store app, these omnichannel capabilities allow us to better serve our guests, while also leveraging inventory across both our store and e-commerce channels.
I also want to highlight our integrated brand building efforts. We are now better able to combine the power of our community model with the improving power of our digital capabilities to better deliver our message to our new and existing guests. In Q2, building on last year's success, we sponsored 10k runs in Toronto and Edmonton. Across both races, we saw over 13,000 runners participate, including 4 Olympians, and garnered 9 million impressions on social media.
Looking forward to Q3, we will continue our global outreach via a collaboration with Francesca Hayward of The Royal Ballet in London, and we are thrilled about our plans to celebrate our 20th birthday, which started this month and continues through September. Without giving too much away, we plan a truly integrated celebration, which includes digital in-store events and a special capsule collection, a fitting way for us to recognize and celebrate our brand over the last 20 years while looking ahead to the next chapter.
Before PJ provides the details on our financial results, I wanted to offer a few final comments. While we are pleased with our current performance, we're laser focused on leveraging this momentum to enable a strong 2019 and beyond. Specifically, we are making a number of investments in the second half of the year, which PJ will speak to that will help us test strategies to potentially scale into next year. These tests consider multiple parts of our business, including experiential retail, digital guest engagement and conversion drivers across all channels. More to follow on this, but we are excited to build on our current success with these investments to help shape our future.
And finally, I'd like to thank Glenn for support during our transition period, and I especially want to thank Celeste and Sun for their invaluable leadership in driving these incredible results. We're now excited to have Calvin on board and look forward to supporting his transition.
And importantly, we'd all like to express much gratitude to our teams and our educators in particular around the world. It is only through their hard work that any of this is possible.
I will now turn it over to PJ.
