Designer Profile
THIRD FORM
A Label with a Feel for Now
Effortless meets refined in Third Form’s signature aesthetic. Founded in Australia and known for its sharp minimalism, this label blends clean tailoring with directional silhouettes, always keeping things polished but never overdone.
The Third Form collection at BELLA n’ BEAR is a curated edit of sleek wardrobe staples and standout pieces—designed to take you from desk to dinner, and day to after-dark with minimal effort and maximum style.
Tailored, Toned, and Textured
Third Form’s strength lies in its modern restraint. Expect structured yet fluid shapes, cut-out details, and unexpected textures—from crushed satin to rib knits and soft tailoring.
Pair a slim-fit Midi Skirt with a sculpted top, or go all-in with one of the label’s understated Neutral Dresses. Whether you’re dressing for a work event or drinks with friends, these pieces let your style do the talking—quietly, confidently.
A Smart Take on Occasionwear
Not every occasion dress needs sequins. Third Form proves that sleek lines and quality fabric speak volumes. These designs hold their own at weddings, parties, launches, or gallery nights—anywhere polished edge is the vibe.
