During the early years of her career, she worked for
Yves Saint Laurent,
Ralph Lauren, and
Christian Dior. Phillips began professionally designing her own pieces in 1989, while still working for Dior. She sold several of her first pieces to
Henri Bendel, where they were featured in the front store windows along Fifth Avenue. The line, a 15-piece collection of suits and evening clothes, was bought by
Saks Fifth Avenue and
Neiman Marcus amongst other specialty stores throughout the US, Canada, and Hong Kong. Phillips, took a hiatus, from designing, in order to spend more time with her family and continued with her illustration. Her new collection consisted of "40 special-occasion pieces made of silk and cashmere" and a scaled-back business model; the line was sold only through trunk shows to her private clients and her website. ==1993 Inaugural Ball gown==
