Formal Maxi Dresses For Every Formal Night

A full-length gown is the classic formal choice, and this collection narrows our wider formal dresses to that silhouette specifically, across every colour we carry.

A Fabric For The Occasion

Satin and mesh both bring a polished evening finish, with jersey for an easier drape, tulle and lace for texture, and beaded finishes for a bit more shine.

For Your Year 12 Formal

If you are shopping for a year 12 formal specifically, a full-length gown is a natural starting point - much of the evening is spent seated before the dancing starts, so a fabric with a little structure through the middle earns its place.

More To Explore

For a defined waist at the same length, browse formal corset dresses, or the wider maxi dresses collection for every occasion at full length. For full-length white, our white maxi dresses come in ivory, oyster and true white.

Designed To Flatter

Every dress here is chosen to drape well at full length, carefully finished so it holds its shape from the first dance to the last.
