• Knit dress: the Vianna mohair wool lace mini dress with ostrich feathers at $1,450.

• Sizes: letter sizes, XS to XL across the range, with each style made in a slightly different spread.

The feather sweater and the embellished knit

Costarellos is known for French lace, crystal embroidery and feminine evening lines, and the knitwear carries the same handwork onto mohair. The Fall Winter 2026 knits use a blend of 50% mohair, 45% polyamide and 5% wool. The polyamide keeps the mohair stable, so the feathers and lace have something firm to sit on. The Pre-Fall 2026 knits, Nemie and Madley, use 48% mohair, 36% acrylic, 9% polyamide and 7% polyester.

The result is a sweater that can do the work of an evening top. Feathers sit at the shoulders of the Lissia, and the Terena and Vianna combine corded lace applique with ostrich feathers. The Madley keeps it quieter with crystals, and the Nemie carries an applique the house calls “Oasis”.

Letter sizes for Costarellos knits

All the knits fit true to size, so take your usual size. The model on the brand site is 180cm and wears size S in the Nemie and Madley sweaters. The spread of sizes differs by style:

The same 180cm model wears FR 36, a UK 8, in Costarellos dresses, which gives a useful guide when you move between French and letter sizes. Mohair has natural loft, so it will feel fuller on the body than a fine merino in the same letter size.

How to dress an embellished sweater up for evening

An embellished knit works at night when the rest of the outfit is sleek. The aim is contrast: a soft, textured top against a smooth, fluid bottom.

• With velvet: the Lissia sweater over the Laudrie velvet maxi skirt ($1,450) gives a full-length black look for a winter dinner at $2,640 in total.
• With satin trousers: the Madley in black with the Nelia satin cigarette trousers ($870) keeps the line narrow and lets the crystals do the work.
• With a crystal skirt: the Terena in off white with the Marice embroidered crystals pencil skirt ($2,430) for a Christmas party and New Year’s Eve.
• The feather top as the statement: the Luneth with the Padra cotton velvet flared trousers ($1,450), a holiday party outfit that keeps legs covered.

Keep jewellery minimal near the neckline when the feathers sit at the shoulder, and choose a slim heel so the volume stays at the top. The full range sits in the sweaters edit and on the Costarellos brand page, and the Luneth sits with tops.

How to care for mohair and feathers

• Check the label first. Feathered and lace-trimmed knits are best taken to a specialist dry cleaner, because water and agitation can flatten feathers and loosen applique.
• Store flat. Hanging a mohair knit stretches the shoulders. Fold it with tissue across the feathers and keep it in a breathable cotton bag.
• Revive the pile. Mohair sheds a little at first. Shake the sweater gently and let it air before wearing.
• Feathers: a short burst of steam from a distance helps a crushed feather recover. Keep perfume and hairspray away from them.
