Mon Renn | Sierra Mini Dress - Plum Swirl
The Sierra Mini is unapologetically of-the-moment. Mon Renn’s exclusive handcrafted plum swirl placement print commands attention before you’ve even left the room, printed across a stretch mesh that fits like it was cut for your body specifically. The colour — a deep, saturated plum with swirling movement — is rich and statement-making without being costume.
A fixed cross-over V-neckline gives the bodice a wrapped, sculptural quality, while artful side waist tucks cinch the silhouette with precision at the waist. The micro-mini length is bold and committed — this is a dress that knows exactly what it is. Fully lined, pull-on.
Style Advise: Wear with strappy barely-there heeled sandals and a small evening bag. Keep accessories in metallics — gold or bronze will lift the plum beautifully. This dress is styled best when the rest of the outfit stays minimal and the dress leads. For cooler nights, a fitted black blazer worn open over the top extends the wearability.
Fit Advise: Our model is 175cm and wears a size AU8. The Sierra Mini is designed in a bodycon fit. Wear true to size for the intended silhouette. The stretch fabric accommodates a range of body shapes.
