From artist Leigh Pennebaker's website:

In the Wire Couture Collection, the power of line is exploited to create dynamic, three-dimensional fashion sketches in wire. Each one-of-a-kind sculpture has its own name inspired by the distinct personality of the dress. No two pieces are alike in attitude or style.

The wire dress (Wire Couture), is entitled "Mathilda." Dimensions are 19.25 inches tall x 10 inches wide, by 10 inches deep.
