Collection: Women's Trouser Socks

Women's trouser socks are thin, dressy socks made to sit smoothly under slacks, tailored trousers and pencil skirts without adding bulk at the ankle. Ours are knit from organic cotton instead of the nylon blends most trouser socks use, finished with a seamless toe that will not rub and a non-slip cuff that stays up through a full workday.

Pick classic solids and ribbed knits for the office, or polka dots, stripes and small prints when you want a little personality between the hem and the shoe. Every pair is one size for women's shoe sizes 6-9 and designed in the USA.

How to choose trouser socks

• Length: crew to mid-calf height, so no skin shows when you sit down or cross your legs.
• Thickness: a fine 200-needle knit keeps the sock thin enough for close-fitting shoes like loafers, ballet flats, oxfords and low heels.
• Fabric: organic cotton feels soft and breathes, which matters in a sock you wear indoors all day.
• Cuff: look for a non-slip cuff that holds without pinching or leaving a deep ring on your leg.
• Color: match the sock to your trousers rather than your shoes to keep the leg line unbroken. Black and navy cover most suiting; grey works with lighter wool and flannel.

Trouser socks vs. dress socks

The two overlap. Trouser socks are the thinnest, most minimal kind of dress sock, made to disappear under a trouser hem; dress socks can be a little longer or bolder. Read our full guide to trouser socks vs. dress socks, or see how to match socks to a suit.

Trouser socks FAQ

What are trouser socks?
Thin, lightweight socks worn with trousers and dress shoes, usually crew to mid-calf length, in dark solids or subtle patterns.

What size are your women's trouser socks?
One size fits women's shoe sizes 6-9.

Will they stay up under trousers?
Yes. The non-slip cuff is made to stay in place all day without squeezing your calf.

Can I wear trouser socks with flats or loafers?
Yes. The fine knit is thin enough for loafers, flats and low heels. Choose a color close to your trousers for a clean line.

Are trouser socks the same as knee-highs?
No. Trouser socks stop at crew to mid-calf height, which is all you need under slacks. Knee-highs reach just below the knee, so they suit boots, dresses and long skirts. See our knee-high socks for women.

How do I wash them?
Machine wash cold on a gentle cycle and tumble dry low. Skip bleach, ironing and dry cleaning. See our care instructions.
