The purpose of this thesis is to provide all of the paperwork, supporting research, renderings, and production photographs that document the costume design for Boom at the Woolly Mammoth Theatre Company in Washington DC. This thesis contains the following: research images collected from a variety of sources to help develop the design for the show and communicate to the director, actors and other designers conceptual ideas for the production (e.g. color palette, clothing silhouette and style); initial rough sketches; final color renderings created during the design development and rehearsal processes; fabric dye samples and swatches for garments built for the production; hair style research that was used to help the actor's develop the play's characters; and periodical reviews of the show. Finally, archival production photos are included to visually document the completed design.
