Texas, Oklahoma, and Indiana are among the states allowing "nonessential" retail stores and malls to reopen.
Stores must follow strict guidelines depending on the state where they are located. In Texas, for example, most reopened businesses must limit visitors to a 25% capacity, putting pressure on margins.
Understanding differing regulations in states and counties is also proving difficult for retailers.
"There's such a big range — and it takes quite a bit time to interpret the differences —rather than have something that is more consistent," Gap Inc. CEO Sonia Syngal told CNN, calling the discrepancies the company's "biggest challenge."
