Whether you're attending a Year 10 formal, Year 12 graduation, or an exclusive ball event in the city, our curated collection is packed with show-stopping styles to suit every vibe.
With sizes from 2–26 and exclusive designers you won’t find in traditional Sydney boutiques, One Honey offers a bold and inclusive range. Think corset gowns, sleek satins, sparkly sequins, and curve-hugging silhouettes that photograph beautifully. 
Our Gold Coast showroom remains a favourite for destination shoppers, but Sydney customers can enjoy our full online store with express delivery, signature on arrival, and over 900+ verified 5-star reviews.
And yes – we register every dress sold so you won’t twin with another guest at your formal. Explore affordable gowns starting from just $99, and flexible payment options including AfterPay, ZipPay, Humm, LayBuy, PayPal, and more. Whether you're searching for a gown in Bondi, Double Bay, or Parramatta, you'll find your dream look right here at One Honey.
