Originally an illustrator and textile designer, Biddle employs a style immersed in broad, luxurious brushstrokes and rich, plush colors to capture the era’s fashion, elegance and simplicity. Biddle intentionally obscures the faces of her subjects so viewers can invent their own romantic storylines. She paints figurative works (often featuring horses), florals, fashion and children’s art. Published worldwide, Biddle's works are featured in numerous corporate and private collections.
