The St. John's Bay line of women's clothing under the JCPenney umbrella and was discontinued by Ron Johnson, former CEO of JCPenney.

However, there are occasional complaints regarding the quality of certain items.
Instead of contacting the manufacturer directly about these issues, another option is to return the clothing item to the store in person. The consumer can visit the customer service desk, explain the issue, and the salesperson will attempt to rectify the situation. If the item was purchased online and the buyer is unhappy with his or her purchase, simply return the item by mail with an explanation.
