Liza Rietz began designing and sewing custom and retail pieces in 2001. She has been a part of Portland’s artistic clothing community from the beginning of her career, participating in multiple group and independent fashion shows in the area. Her designs have been available nationally in high-end boutiques in Portland, Seattle, Los Angeles and Washington DC. Liza Rietz designs are currently available for both custom and retail at her studio/store "liza rietz" in Portland, Oregon.

Rietz’s modern designs are structured yet feminine, detailed yet wearable, and are created individually, not mass-produced. Rietz designs two small lines annually, producing small batches of each individual design. Though her collections adhere to the seasons, her lines are not season-specific. Instead, Rietz focuses on designing clothes that are versatile and that easily translate to any time of year.

Rietz’s designs are made out of all natural fabrics including cottons, linens, silks, and bamboos. With a small production run of each line, the individuality of each piece exemplifies how clothing can be artistic and expressionistic as well as functional.
