"We red bottom boots share the same aesthetic appreciation for life," she says. That aesthetic led her to produce an earthy collection that will show at Swampspace, the Design District’s sole remaining alternative haven, rather than at Prada, Cartier, Sebastien James, Christian Louboutin, or any of the other high end fashion emporiums in the red bottom shoes area.
