By Phia

Rat & Boa began in Thailand in 2015, founded by best friends Valentina Muntoni and Stephanie Bennett, whose contrasting styles became the label's creative engine. The brand first built its following with bold resort dresses, sheer fabrics, expressive prints, and flattering silhouettes, then expanded into tailoring, knitwear, leather, and workwear separates. Rat & Boa's direct-to-consumer online model keeps the collections close to the founders' point of view, with pieces for holidays, parties, and a more dressed-up everyday wardrobe.
