What Denier Tights Should I Wear? 7 to 200 Denier Explained

Quick answer: Denier measures the thickness of the yarn in tights. The lower the number, the sheerer the tight: 7–20 denier is sheer, 30–60 is semi-opaque, 80+ is fully opaque, and 200 denier or thermal tights are for winter. For everyday winter wear in the UK, 80–200 denier is the sweet spot; for a barely-there summer leg, 7 denier is the sheerest you can buy.

What does denier actually mean?

Denier is the weight in grams of 9,000 metres of the yarn used to knit the tight. In practice it tells you how sheer or opaque — and how warm — a pair of tights will be. It is the single most useful number on any tights packaging. Every pair in our fashion tights collection lists its denier, so you can judge warmth and sheerness at a glance.

7 denier tights: the sheerest you can wear

7 denier tights are the lightest hosiery made — closer to a veil than a fabric. On the leg they read as bare skin with a soft, even finish, which is why they are the classic choice for summer weddings, garden parties and anywhere you want polish without visible tights. Because the yarn is so fine, look for a “stop” or ladder-resist knit: our Penti 7 Denier Stop tights are knitted so a snag doesn't run into a full ladder. Black 7 denier tights give a sheer, smoky leg rather than solid colour; if you want visible black, step up to 15–20 denier. For a touch more durability with almost the same look, the 15 Denier Stop is the everyday sister.

What denier tights for winter?

Go for at least 80 denier — our 80 denier opaques are the everyday winter staple. For real cold, choose 200 denier micro tights or thermal hosiery, which trap warmth like leggings while keeping a tights silhouette.

What denier tights for the office?

15–20 denier is the classic professional sheer — see our premium 20 denier tights. If your office is cold or you prefer more coverage, 40–60 denier semi-opaques read just as polished.

What denier for maternity tights?

Opaque 80 denier is the most comfortable choice in pregnancy: it is warm, forgiving over the bump and holds its colour when stretched. The Italiana 80 Denier Maternity Tights are cut with a soft, stretchy waistband designed to sit comfortably over or under the bump.

Does higher denier mean better quality?

No — denier measures thickness, not quality. Quality shows in the knit, the waistband, reinforced toes and fibre content (look for elastane for stretch and recovery). A well-made 15 denier can outlast a cheap 80 denier.

FAQs

What do 7 denier tights look like?

Almost invisible: a faint, even sheen with no visible colour. Nude shades disappear on the leg; black 7 denier reads as a sheer grey smoke rather than solid black.

What does 80 denier mean?

80 denier means 9,000 metres of the yarn weigh 80 grams — thick enough that no skin shows through. It is the standard “opaque” and the most popular denier for UK autumn and winter.

Is 100 denier much thicker than 80?

Slightly. Both are fully opaque; 100 denier feels a touch warmer and more matte, and hides more when stretched over larger sizes. If you are between the two, choose 100 for warmth and 80 for a sleeker finish.

Are 40 denier tights see-through?

Slightly — 40 denier shows a hint of skin in bright light. For a fully solid black leg, choose 80 denier or above.

What denier are fishnet tights?

Fishnets aren't measured by denier in the same way — the open knit defines the look. Browse our fishnet collection for classic and wide-net styles.
