Weather plays a pivotal role in how retailers choose which categories of clothing to sell during a particular season.
UBS expects the country will see above-average temperatures over the next three months, which could negatively impact apparel and footwear sales.
"Softlines companies plan to sell colder weather categories (e.g. sweaters and coats) during this time of year," the firm said. "When the weather is cold, it gets consumers in the mood to buy these items at full price. When the weather is warm, the opposite effect occurs."
