About this product
Mustard Seed gives UGG’s Classic Ultra Mini Biarritz Boot a warm, golden-brown colour direction, creating a soft contrast with cream, denim and other muted shades. The women’s design pairs the Classic Ultra Mini silhouette with the Biarritz name and dates from 2025. Its restrained palette keeps the boot visually simple while adding a gentle seasonal accent.
