Old Navy in Rockville, MD, offers a wide range of fashionable clothing for the whole family, including trendy maternity wear, stylish options for women, men, and kids. Customers appreciate the good quality and reasonable prices of the clothing, particularly during sales. The store features a solid selection of plus sizes and colors, making it easier for shoppers to find the right fit. Reviews highlight the helpfulness of staff members, especially one named Kristen, who provided excellent customer service over the phone, and another associate in the fitting rooms who assisted with sizing. However, experiences can vary; some customers reported poor service from other associates and issues like security tags not being removed. The store's organization could also improve, as clothes were often found on the floor, creating hazards for those with mobility issues. Additionally, the checkout process has drawn criticism for requiring a PIN for debit card transactions, which some shoppers find inconvenient. Overall, Old Navy remains a popular choice for inexpensive clothing, but there are areas for improvement in service and store maintenance.
