Description
The Sidonie is what a warm morning asks for: shoulders tied loosely, back open to the air, nowhere in particular to be.
Cut from pre-washed natural linen, it keeps a soft, lived-in hand from the first wear. The undyed flax tone sits quietly beside everything you already own.
Fit notes: The Sidonie runs true through the bust, with an A-line skirt that flares gently from the waist. The tie shoulders adjust the fit up top; loosen or shorten them to suit your frame. Between sizes on top? Take the smaller; the ties give you the rest of the room. Find your measurements in the Size Guide.
Details: Mini length, hits above the knee · Straight neckline · Tie shoulders · Open back · Sleeveless · Machine wash cold, line dry · Pictured in Oat Milk
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
100% European linen, garment-washed for softness. Machine wash cold, line dry, warm iron. It gets better with every wash.
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. Worn for years.
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.”
