Thanks, David. And thank you for joining us. After the market close today, we issued our quarterly shareholder letter with more details on our results and strategies, as well as the press release announcing the appointment of Dan Jedda as our new Chief Financial Officer. Today, I'll be sharing our first-quarter results and highlighting three key themes that position us to accelerate top line and client growth in the year ahead. First, our business has great momentum and reached several multiyear highs in Q1. Second, the secular shift to online shopping and the share gain opportunity we've discussed in past quarters is well underway, and we expect accelerating active client growth to play a significant role in our full year outlook. And third, we're enhancing our Fixes and direct buy offerings to expand our addressable market, deepen client engagement, and grow wallet share over time. Before I dive into these themes, let me first discuss our Q1 results. In Q1, we generated net revenue of $490 million, reflecting 10% growth year-over-year and 11% growth quarter-over-quarter. We delivered net income of $9.5 million and adjusted EBITDA of $6.9 million. During the quarter, we grew our active client count to nearly 3.8 million. This represents a year-over-year increase of 347,000 clients or 10% growth and a quarter-over-quarter increase of 240,000, our highest sequential client addition on record. This surge of new clients who are still early in their spending journey with us resulted in an expected decrease in year-over-year net revenue per client of 4%. Even early in their journey with us, these new clients have demonstrated very strong purchase behavior in their first fixes that we believe to be a strong signal of feature satisfaction, retention, and lifetime value. Q1 was a quarter that saw great momentum in client growth and in our business more broadly. Our offering continues to benefit from strong product market fit. In a time period where many traditional brick-and-mortar retailers are still experiencing double digit year-over-year revenue declines in their most recent quarter, we delivered an increase of over 240,000 net active clients quarter-over- quarter, a return to double-digit, year-over-year active client growth which we expect will increase further this fiscal year. And their very first experience with us, these recently acquired Fix customers are demonstrating both strong purchase behavior and satisfaction. We previously shared a measure that we internally refer to as a successful first Fix, which we define as the percent of clients who purchase at least one item in their first Fix and look forward to their second Fix. In each of the last two quarters, nearly 80% of our first Fixes met these criteria, which is the highest level we've seen in five years. Even as we acquired a high volume of clients, we're very pleased that we're able to meet their needs and preferences. The strength of these recent cohorts are due in part to our ability to shift our inventory to meet the client in the moment, but also our longer-term efforts in improving our recommendations by leveraging our growing data set to bolster our style graphs and power our algorithmic models. We believe that establishing a favorable first Fix outcome is a strong indicator of future client engagement and retention that will serve as a tailwind in the quarters to come. We saw strong client outcomes in our newest clients and also in our broader existing client base. We're pleased to share that across our entire Fix offering, we’ve increased success rate every year on record. And in Q1, we delivered our highest level yet. We believe this strength is driven by our ability to leverage data to generate insights that allow us to relentlessly adapt our inventory assortment and continually strengthen our recommendation. In Women's for example, we've grown our athleisure assortment as a percent of our women's inventory by over 150% compared to pre-COVID levels, helping us to serve elevated demand for these products and meet our clients’ work from home needs. In Kid's, we've used sourcing speed to our advantage. We're now sourcing a meaningful portion of some of our most in-demand styles using a rapid sourcing model where product arrive to our distribution centers in as little as 10 weeks. This contributed to a strong back-to-school season in which we grew first Fix shipments by 60% year-over-year. We've also reacted to the current environment by expanding our assortment of more affordably priced products across categories, which have resonated well with women's and then clients and led to outside success rates. As we look ahead, we have growing confidence that our track record of strengthening personalization capabilities paired with our nimble supply chain will allow us to deliver better client and business results. As we look to the remainder of fiscal 2021, our strong foundation of client and business trends sets the stage for the quarters ahead. We are pleased to reinstate annual guidance that reflects the momentum we're seeing. As Mike will discuss later, we expect to deliver net revenue growth of 12% to 14% year-over-year in Q2 and to drive further acceleration in the second half of the year resulting in full year revenue growth of 20% to 25% year-over-year. There are several drivers underpinning this outlook but most notable is our expectation of further acceleration of our active client growth. While the apparel industry is currently contracting, we expect to take share and drive higher new client signups as the relevance of our model of personalized discovery and convenience grows. In Q1, we delivered first Fix growth exceeding 25% year-over-year. As the large majority of our new clients choose to receive Fixes on a recurring cadence, we expect this will drive strong engagement and repeat purchase behavior in upcoming quarters. In addition, we shared in September our plans to hire over 2,000 stylists outside of California, and we're pleased to share that due to such strong demand for our styling role, we’ve already met this hiring target and feel well positioned to serve higher Fix demand in the remainder of fiscal 2021. In addition to our strong outlook for Fix demand, we believe that direct buy will serve as another catalyst as we attract new clients, convert prospective clients, and reactivate lapsed clients. We've continued to see direct buy’s penetration grow across our men's and women's client base, and we plan to introduce it to new and prospective clients later this fiscal year. These strong trends we've seen in our business combined with ongoing market share shift to Stitch Fix gives us excitement for the quarters ahead. In Q1, the combination of record quarterly client additions, strong auto ship retention, multiyear highs and successful first Fix rate and our highest success rates to date demonstrate the resonance of our offering and the power of the personalization engine that fuels our business. With that, I'll hand it over to Elizabeth to share more on the enhancements we're making to our direct buy and Fix experiences, as well as some of the exciting marketing initiatives we're investing in to capitalize on the retail share shift that is under way.
