The Third Form Crush Bias Classic Slip in Gun Metal is a bias-cut slip dress designed for cocktail evenings, dinner dates, and considered evening occasion dressing. Cut from a premium Naia™ Eastman 100% acetate in a sophisticated gun metal tone, this slip dress drapes cleanly across the body with the fluid movement that bias cuts allow.

A straight square neckline shapes the front for modern proportion, while double fabrication on fixed straps provides quiet support across the shoulders. The body is lined for a smooth feel against skin, and the 120cm length falls into elegant midi territory. Discover more bias silhouettes in our Midi Dresses edit or browse the full Third Form range.

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.
