Backless Dresses

The Sienna Gown is a breathtaking statement piece, designed for those who love elegance with a touch of drama. Crafted from 100% pure, flowing silk, this gown offers a relaxed, oversized fit that drapes effortlessly. The high neckline is adorned with a striking, multidimensional floral embellishment, adding a bold yet feminine touch. A luxurious silk bow fastens at the neck, with long, flowing tails that cascade beautifully for added sophistication.

The fabric is soft, shimmering, and sensual against the skin, leading to a daringly low, open back for an ultra-sexy allure. 

Designed for effortless wear, the Sienna Gown is a slip-over style with no zippers—pure luxury, pure elegance.

Please note: We have the mini version of this dress and not the full length.

The Opera Gown - Crafted with incomparable elegance, our Opera Gown embodies a graceful and timeless aesthetic. An opulent silhouette that nods to the decadence of an evening soiree at the Grand Palais, from an era gone by. 

Embracing a flair for drama & grandeur, the Opera plays carefully with modern elegance. Featuring a high neckline, tie back halter and asymmetrical silhouette, this stunning billowing pleat full-length dress will transform you for an evening to remember.

Due to the delicate fabric, there may be some minor pulls consistent with wear but due to the heavily pleated fabric this is not hugely noticeable once on. Reach out anytime if you’d like to see photos before booking.

BEST FIT - 6 on tag would fit a 6 - 10.
