A tight is sheer if it is between 8 and 25 denier. The lower the number, the finer the yarn and the more skin shows through. At 15 denier you get a clean, transparent finish. At 8 denier the leg looks close to bare. From 30 denier up, a tight starts to read as semi-sheer, then opaque at 60 and above.
This guide covers which denier does what, how to choose between a nude sheer tight and a black one, and why a fine tight does not have to ladder the first time it catches. Every Heist sheer is knit as a single piece and set with anti-snag fusion technology, so the yarn holds when it snags.
What makes a tight sheer
Denier measures the weight of the yarn, not its quality. A sheer tight sits between 8 and 25 denier, where the yarn is fine enough to let skin show through. When naming our tights, we've kept them to their denier to ensure it's easy to decipher how the tight will appear on your skin once it arrives at your door. The Fifteen sits at 15 denier: transparent, even, with no shine to give it away. The Bare Nude drops to 8 denier for a close-to-bare finish, giving a perfectly flawless finish.
Fine yarn is the most delicate, which is where most sheers fail. Heist sets every sheer with anti-snag fusion technology during our production process, so a snag on our tights stays as just a catch instead of running the length of your leg. Read denier decoded for the full breakdown on what denier means, or the opaque tights guide if you want more on fuller-coverage tights.
The sheer tights, by denier
The Bare Nude
8 denier, the finest we make. Seven shades, derived from data from 100,000 women, with a reinforced panty section for wear that lasts.
Good for: a bare-legged finish when you would rather not go bare.
The Fifteen
15 denier, ladder-resistant, knit from recycled yarn. The hand-sewn adaptive waistband hugs without digging or rolling, and the gusset-free leg does not sag.
Good for: the everyday sheer that runs from desk to dinner.
The Nude Sheer
18 denier, seamless, in seven shades matched to skin from fair to deep. A barely-there look with the security of a tight.
Good for: a natural leg under dresses and skirts.
The Thirty-Five
35 denier, semi-sheer, knit from Q-Nova® by Fulgar recycled polyamide. Seamless, gusset-free, with the adaptive waistband that holds all day. Made in Italy.
Good for: cooler days when you want a little more cover.
Sheer or semi-sheer: which to choose
The choice comes down to how much leg you want to show and how warm you need to be. Sheer tights, from 8 to 25 denier, keep the look of bare skin. The Bare Nude, The Fifteen and The Nude Sheer all sit here. Semi-sheer starts at 30 denier, where The Thirty-Five gives a fraction more cover without reading as opaque.
For a nude leg, match the shade to your skin rather than the tight to your outfit. For black, 15 denier reads as a clean sheer line. Go to 35 denier when you want the colour to hold. Deciding on cover? The opaque tights guide picks up at 60 denier and above.
Why a fine tight does not have to ladder
Sheer yarn is fragile by nature. Standard hosiery yarn is a single strand of elastane wrapped once in nylon, which is why most sheers ladder the first time they catch. Heist double-covers the yarn and sets every sheer with anti-snag fusion technology. Under heat, the finish fuses the fibres so a snag holds instead of running. Think of this as the setting spray for tights; the final step that holds everything in place. The hand-sewn adaptive waistband does the rest, with no digging, no rolling and no sagging through the day.
We tested the range across 196 samples with 67 women before it went into production. A pair that lasts multiple seasons costs less per wear than a supermarket three-pack you replace every month. Fine does not have to mean disposable.
Styling sheer tights
A sheer black tight is the quietest way to finish an outfit. It closes the line between hem and shoe without adding weight. A nude sheer disappears under tailoring and reads as skin in a photograph too. For warmer months, a fine denier holds under a midi without overheating, which is the case the tights in summer guide makes in full.
If you want light shaping with your sheer, The Fifteen Contour adds graduated compression through the waist and leg while keeping the 15 denier finish. For a nude leg done properly, the nude tights styling guide has the shade logic.
Sheer tights: your questions answered
What denier are sheer tights?
Sheer tights run from 8 to 25 denier. At 8 denier the leg looks close to bare. At 15 denier you get a clean, transparent finish. From 30 denier up a tight reads as semi-sheer, then opaque at 60 and above.
What are sheer tights?
Sheer tights are fine, transparent tights that let skin show through. They give the look of a bare or evened leg with the security and light warmth of a tight. Heist sheers span 8 to 18 denier across The Bare Nude, The Fifteen and The Nude Sheer.
Can you wear sheer tights in summer?
Yes. A fine denier holds under a dress without the weight of an opaque tight, which is why nude sheers work through warmer months. See the tights in summer guide for how to wear them when it is warm.
Should I wear sheer or opaque tights?
Sheer for the look of bare skin and lighter cover. Opaque for full colour and warmth. Sheer sits at 8 to 25 denier, opaque at 60 and above. The opaque tights guide covers the heavier end.
Do sheer tights keep you warm?
Less than an opaque pair, but more than bare legs. A 15 to 18 denier sheer adds a light layer without heat, which suits transitional weather and warm rooms. For real warmth, move up to 60 denier or higher.
What are the best sheer tights in the UK?
The pair that does not ladder the first time it catches. Heist sets every sheer with anti-snag fusion technology and double-covered yarn, so a fine 15 denier lasts multiple seasons. Compare the range in the sheer tights collection.
