Stitch Fix is an online personal styling service in the United States. Founded in 2011, Stitch Fix went public in 2017. Immediately after the initial public offering, Stitch Fix was valued at $1.6 billion. As of February 2018, the company was valued at $2 billion.
Stitch Fix was founded in 2011 by former J.Crew buyer Erin Morrison Flynn and Katrina Lake. The business was originally called Rack Habit, and was initially run out of Lake's apartment in Cambridge, Massachusetts.  The company began by catering only to women, but it has subsequently expanded to men's clothing, plus sizes, maternity wear, and kids.
Stitch Fix started to be profitable in 2014. In July 2016, the company ended its fiscal year with recorded sales of $730 million, and in May 2017, the company had raised $42 million from outside investors. As of May 2018, they had 5,800 employees including 3,000 stylists and 75 data scientists. 
In October 2018, several class action lawsuits were brought against Stitch Fix alleging that the company violated federal securities laws by making misleading statements about its growth prospects.
Stitch Fix is a personal styling service that sends individually picked clothing and accessories items for a one-time styling fee. Customers fill out a survey online about their style preferences. A stylist at the company picks five items to send to the customer. Stylists pick items based on a customer's survey answers and any access the customer gives them to their social media outlets such as Pinterest. The customer schedules a date to receive their items, which is referred to as a "Fix". Once the shipment is received, the customer has three days to choose to keep the items or return some or all of them. If the customer keeps at least one item, the initial styling fee is credited towards the cost of the item. In addition to the styling fee being credited, if the customer decides to keep all five items, the customer receives 25% off the total cost of the items. Customers choose the shipping frequency, such as every two weeks, once a month, or every two months. The company also supports integration with Pinterest boards, allowing customers to add photos of fashion looks that they like. These boards may be viewed by a Stitch Fix stylist.
In 2019, Stitch Fix was featured on Wired magazine reporting astrophysicists leaving academia for Silicon Valley, where Eric Colson, Stitch Fix's chief algorithms officer emeritus, describing the background of the data science team in Stitch Fix, said, "Astrophysics is our number one domain. Most folks have a PhD in a quantitative field, but if we did a histogram, I think astrophysics is number one. They teach math really well - a lot of physicists are better mathematicians than mathematicians. They also teach coding well. They're better computer scientists than most computer scientists". The same article reported that "the Stitch Fix team uses something called eigenvector decomposition, a concept from quantum mechanics, to tease apart the overlapping “notes” in an individual’s style.".
