The ‘Cosmos Secret’ set has the soft buttermilk warmth of shortbread cooling on a windowsill, all golden edges and unhurried afternoons.
We’ve cut both pieces from a special crinkle-textured linen blend with a subtle tonal weave, lightweight and soft against the skin and wonderfully easy to live in. Beneath the dress, a cotton glass-voile lining keeps everything cool, breathable, and smooth, with nothing scratchy against you from afternoon into evening.
The ‘Cosmos Secret’ dress wears its romance in the detail. Its front bodice is finished with delicate pintucking, precise and beautifully worked, while panels of specially dyed lace in varying widths trace the bodice, waist and tiered hem for that collected, vintage feel. Down the centre front, self-covered fabric buttons add a quiet handmade charm, the kind of finishing touch that rewards a second look.
Comfort is sewn in everywhere it counts. A discreet side-waist zip makes slipping in and out effortless, adjustable strap sliders let you tune the fit to your shape, and a hidden elasticated waist panel gives gentle stretch so nothing digs or pulls.
The ‘Cosmos Secret’ bolero is the set’s gentle scene-stealer, its neckline and cuffs edged in scalloped wave lace that curves along every line with real craftsmanship. The prettiest details, after all, are often the most carefully made.
Worn as a set, they have a gentle, garden-party glow. Set the dress loose on its own for sun-warmed afternoons; drape the bolero over a simple cami another day, and its scalloped-lace edging brings quiet romance to the everyday.
*Carefully curated from a limited or archive selection. All sales are final.
• Dry cleaning is the best way to extend the life of your item.
• Hand wash in cold water, using a gentle detergent. Gently and slowly swish the garment then rinse with cold water. Remove excess water by rolling the garment in a towel and gently pressing to absorb lingering moisture. Ensure the garment keeps its shape by laying flat or hanging to dry.
• Use a steamer to get out creases in your item or simply iron inside-out on low heat, putting a cloth between the fabric and the iron.
