Eterne Care Guide 2026: How to Wash Cashmere, Silk, Jersey and Rigid Denim

You finally bought the sweater. It arrived folded in tissue, the cream knit so soft you wore it straight out of the box. Two weeks later there's a coffee drip on the cuff, and you're standing at the washing machine with the label between two fingers, wondering whether you're about to ruin a $265 purchase.

Good news: Eterne (styled ÉTERNE) prints clear care instructions on every product page, and they're not all "dry clean only." Olivia Reviews read the fabric and care details across the Los Angeles label's tees, butter rib, jersey, silk, French terry, denim and cashmere in October 2026, and sorted them into a routine you can actually follow.

Quick take: Most Eterne cotton, cotton modal, butter rib and French terry pieces can go in the machine on cold and tumble dry low. Jersey and the cotton-cashmere Francis want a delicate or gentle cycle and dry flat. Silk, 100% cashmere and the down puffer are dry clean only. Denim should be washed and dried inside out. And because returns require items to be unworn with tags attached, decide on fit before the first wash. Shopping first? See today's Eterne deals.

Read the label first: Eterne's three care families

Every Eterne listing has a "Fabric" tab with the composition and care line. Across the pieces Olivia Reviews checked, they fall into three groups:

Machine wash, tumble dry low: cotton modal, butter rib and French terry. The line usually reads "Machine wash cold with like colors. Do not bleach. Tumble dry low. Cool iron."
Gentle cycle, dry flat: soft jersey, liquid jersey, cotton twill, the Ringer Baby Tee and cotton cashmere.
Dry clean only: silk, 100% cashmere, the viscose Constance Top and the Down Puffer.

Two rules apply to every group: no bleach, and cold water. Not one listing Olivia Reviews read called for warm or hot.

Butter Rib: the easy-care favorite

The brand's fabric guide describes Butter Rib as having "a butter-soft feel, subtle texture, and sculpting fit," with a second-skin sensation. It's also one of the simplest fabrics to look after. The Long Sleeve Henley ($205), for example, is 95% rayon and 5% spandex, slim, with a button placket and raw-edge hem. Its care line: machine wash cold with like colors, no bleach, tumble dry low, cool iron.

Keep it looking new: the low dryer setting is the key word. A rib knit with spandex holds its shape best when it isn't blasted with heat, so if your dryer runs hot, pull it out while it's still slightly damp.

Cotton modal and French terry: wash with like colors

Eterne's everyday tees and sweats are the workhorses, and their care reflects it. The cotton modal Lounge Pant ($175, 50% cotton and 50% modal, with the brand's 33¼-inch inseam) and the Oversized V-Neck Sweatshirt ($235, 77% cotton and 23% modal French terry with an embroidered logo) share the same instructions: machine wash cold with like colors, no bleach, tumble dry low, cool iron.

"With like colors" matters most for saturated shades like Forest, Washed Navy and Mushroom. Wash darks together, and the ivory and cream pieces separately, so whites stay bright.

Jersey: delicate cycle and dry flat

Jersey is where many people go wrong, because it looks as tough as a tee but drapes like something finer. The Wrap Top ($225) is a 96% modal, 4% spandex soft jersey with adjustable ties and double-lined fabric. Its label asks for a delicate cycle, cold, with like colors, no bleach, then dry flat and a cool iron. The liquid jersey pieces, such as the Elsa Midi Skirt and Anouk Top (96% viscose, 4% elastane), carry the same delicate-and-dry-flat instructions.

Why dry flat: hanging a wet, stretchy knit lets gravity pull it longer. Lay it on a towel or a mesh rack, smooth the seams, and let it air dry.

Silk: dry clean only

The fabric guide calls Eterne's silk "soft, substantial, luxurious," with a smooth, fluid texture and polished sheen. The Mila Camisole ($295) is 93% silk and 7% spandex with adjustable straps, and its care line is short: dry clean only. The same goes for the slightly sheer viscose Constance Top.

Since silk goes to the cleaner, protect it between trips: wear a camisole under a sweater or blazer rather than directly against perfume or deodorant, and hang it to let any creases relax.

Rigid denim: inside out, every time

Eterne's jeans are 100% cotton rigid denim, and the care line starts with a specific step: "Wash and dry inside out." The Saint Jean ($495), a relaxed boyfriend fit in lightweight rigid Japanese denim with a 32-inch inseam and button fly, should be machine washed cold with like colors, with no bleach, then hung to dry or tumbled low.

Turning jeans inside out protects the face of the denim, which is what keeps a wash like Light Indigo looking even. Hang drying is the gentler of the two drying options the brand gives.

Cashmere: know which Francis you own

This is the most important care distinction in the whole store, because the Francis Sweater comes in two versions that look alike:

Francis in cotton cashmere ($265): 95% cotton, 5% cashmere, lightweight. Care: machine wash cold, gentle cycle, no bleach, dry flat, cool iron.
Francis in 100% cashmere ($375): midweight, in shades like Red. Care: dry clean only.

Eterne's other all-cashmere pieces Olivia Reviews checked, including the Cruz Pant and Dillon Beanie, are also dry clean only, and so is the duck-down Down Puffer. If you want a cashmere-touch sweater you can wash at home, the cotton-cashmere Francis is the one to pick.

Before the first wash: protect your return window

Eterne's FAQ accepts refunds or exchanges within 30 days of receipt, but items must be new and unused with all original tags attached. In practice that means trying a piece on at home, checking the fit in good light, and only then cutting the tags and washing it. Return shipping is deducted from refunds, while exchanges for like items ship back free by ground. Final Sale pieces can't be returned, exchanged or credited, and international returns aren't accepted.

Eterne care FAQ

Can I put Eterne tees in the dryer?

The cotton modal and French terry pieces Olivia Reviews checked say tumble dry low. Jersey pieces and the Ringer Baby Tee ask for a delicate cycle and drying flat or on low if needed.

Is all Eterne cashmere dry clean only?

No. The 100% cashmere pieces are, but the cotton-cashmere Francis Sweater is listed as machine wash cold on a gentle cycle, dry flat.

How should I wash Eterne jeans?

Inside out, cold, with like colors and no bleach, then hang dry or tumble dry low, according to the denim listings.

Where are Eterne clothes made?

The listings show a mix: many cotton, French terry, rib and denim pieces say Made in USA, while silk, cashmere, liquid jersey and some twill pieces say Made in China.

Final verdict

Eterne's clothes are easier to care for than their prices suggest. Cold water and no bleach cover almost everything, the everyday tees and sweats handle a low dryer, and only the silk, pure cashmere and outerwear need a cleaner. Learn the label once, keep the tags on until you're sure of the fit, and your pieces will keep their shape for years. Ready for the next one? See today's Eterne deals.
