The Fearless 19-year-old chart-topper with a sunny disposition is often seen in the summertime frocks.
"One of my favorite things to wear is a sundress, so I loved designing this new line with l.e.i.," she said in a statement. "It's fun to find great clothes that are affordable, so hopefully fans will be happy to see my sundresses at Wal-Mart."
Three styles of the 100% cotton creations will be available for the initial launch, with two more joining the collection on March 1.
