Explore Year 12 Formal Dresses

Your Year 12 formal is the big one. Find the gown you've been dreaming about, from full ball gowns and sculpted corset dresses to sleek mermaid gowns and sparkly dresses.

Plan ahead: the most popular styles and sizes sell out fast in formal season, so start shopping early and order well before your event. Shopping for Year 11? These styles suit Year 11 formals too, and our Year 10 formal dresses cover semi formals.

Shop by colour with black, red, pink and blue formal dresses, or find your fit in plus size and petite styles. See all school formal dresses and prom dresses.

Worried someone else will wear the same dress? Every dress order is added to our Dress Register, so we can help prevent two customers wearing the same dress to the same event.

Finish your look with our clutch bags and accessories, and check our shipping page for delivery options Australia-wide and to New Zealand.
