Description
The Rosanne's deep V-neck and delicate shoulder ties offer a fluid line. A silhouette that drapes softly, adapting to your form with ease.
Sewn in pure satin in a rich olive green, it offers a soft hand and a luminous drape. The material moves with a subtle whisper, feeling cool against the skin.
Fit notes: The Rosanne is cut to skim the body, with the deep V-neckline designed to flatter without revealing too much. The shoulder ties allow for an adjustable fit through the bust. Between sizes? Consider your bust measurement for the truest fit. Find your measurements in the Size Guide.
Details: Midi length, hits mid-calf · V-neckline · Sleeveless · Gathered bust detail · Gentle hand wash cold or dry clean · Do not tumble dry · Pictured in Olive Mist
The Bielline Difference
One dress, two sizes. The bodice is cut to your top size, the skirt to your bottom, made to your measurements after you order. How it works
Fabric & Care
Satin, chosen for the way it catches light. Dry clean, or hand wash cold with a gentle detergent — never wring or soak. Press water out between two towels; iron low on the reverse.
Shipping & Delivery
Your dress is cut and sewn after you order: 7–14 days in production, then tracked shipping to the US and UK. 14–28 days door to door.
Returns & Exchanges
We make it fit. If the cut is our error, we remake it or refund you in full. If your measurements were off, we send a $30 tailor credit toward a local adjustment, so the dress still ends up fitting you.
The Bielline Difference
One dress. Two sizes. Yours alone.
Choose your top size
The one that fits your shoulders and bust. Nothing pulls, nothing gapes.
Choose your bottom size
The one that fits your waist and hips. The drape falls exactly where it should.
Made for you, to your sizes
Cut and sewn to your combination, finished by hand, so the first wear feels like the tenth.
From the atelier
Deliberately designed. Effortlessly you.
Ten pieces a season, each cut after you order it and finished by hand with French seams. Made to be reached for, not saved for.
Morning meetings to dinner outside: one dress, no costume change.
“It moves with me, and it fits exactly where it should.”
