The opulent mystique of Egypt in the Twenties inspired Rachel Roy this season and could be seen in the use of antique gold and textural treatments. A crocheted dress and jacket had a metallic varnish that suggested chain mail, and a long and lean strapless gown was done in a graphic jacquard. Not everything gelled. Two frumpy tea-party dresses seemed particularly out of place among Roy’s otherwise elegant, sophisticated clothes, such as a deep purple coat and a simple black dress with subtle power in its shoulder and sleeve. In fact, the collection’s best moments came when the decorative effects — the tricky lace panels and British colonial references — were stripped away.
