Leggings vs tights comes down to one question: can the garment go out on its own? Leggings are opaque, footless stretch pants that you can wear as your only layer below the waist. Tights are hosiery: usually sheer or semi-sheer, often with a built-in foot, and made to be worn under a skirt, a dress or a long top. In practice, leggings belong with your pants, and tights belong with your socks, even when the two look alike on a hanger.
The two get mixed up because they share a silhouette: both are snug, stretchy garments that pull on at the waist, and the words themselves overlap from one country to another. This guide gives you three quick tests that settle any pair in your drawer and a side-by-side table that adds stockings and pantyhose. It ends with an honest look at fishnet-print leggings, which are made to look like tights but pass every test as leggings.
In brief: the quick answer in four checks
- ✓You can see skin through it at rest: it is tights, or another kind of hosiery.
- ✓It has a sewn-in foot: it is tights. No foot proves nothing, because footless tights exist.
- ✓You would happily walk to the shops in it with a short top: it is leggings.
- ✓It is sold by denier: it is hosiery. Leggings are not sold by denier at all.
What are tights?
Hosiery is the family of fine knitted leg coverings worn close to the skin, such as socks, stockings, pantyhose and tights. Tights sit in the middle of that family, covering the hips, the legs and in most cases the feet in one piece. They are usually knitted from fine nylon and elastane yarns that range from almost invisible to completely opaque.
The word changes meaning across the Atlantic, because in British English tights are what Americans call pantyhose, and the Cambridge Dictionary entry for tights marks the UK sense with "US pantyhose" right beside the definition. Its American entry describes a stretch garment that covers the body below the waist, worn especially by dancers. That split explains why a British runner says "running tights" for what an American calls running leggings, so on a UK or Australian website, "tights" often just means leggings.
What are leggings?
Leggings are close-fitting stretch pants with an elastic or knit waistband, no fly, no foot, and a fabric dense enough to wear without anything over it. They come plain or printed, in lengths from the ankle to the calf, and they work for the gym, errands, travel and lounging. Our guide to what leggings are covers the fabrics and cuts in full. For this comparison, what matters is that leggings are built as outerwear, while tights are built as a layer.
The 3 tests that tell leggings and tights apart
Most guides list a dozen loose differences, but you only need three tests, taken in this order. If a pair fails the first one, you can stop there.
Test 1
Can you see skin through it, standing still?
Hold one leg of the garment up to a window without stretching it. If you can see daylight or your hand through the fabric, you are holding hosiery, and its denier number tells you how sheer it will look on the leg.
Denier is a unit of yarn weight equal to one gram for every 9,000 meters of yarn, which the NIST Guide to the SI conversion table lists as 0.000111 grams per meter. A lower number means a finer, more see-through yarn.
As one hosiery maker's scale puts it, 15 to 20 denier is sheer, 30 to 40 is semi-opaque and 50 to 80 is opaque (Fogal denier guide). For example, 15 denier tights show the leg clearly, while 60 denier black tights look solid from a distance. Leggings are never sold this way: no legging label says "40 denier", because a legging is a knit fabric made to be fully opaque, not a fine yarn made to show skin.
See-through: tightsOpaque: go to Test 2
Test 2
Does it have a foot?
A sewn-in foot, often with a reinforced toe and heel, is the clearest sign of tights, while leggings stop at the ankle or above it. The test only works one way, though: footless and stirrup tights are common, and stirrup leggings exist too, so a pair without feet still needs Test 3. In a 1991 classification ruling, US Customs called stirrup feet "inconclusive" for exactly this reason, since "both trousers and tights may possess such features" (ruling HQ 950101).
Full foot: tightsFootless or stirrup: go to Test 3
Test 3
Would you wear it with nothing over your hips?
This is the test that settles every borderline pair. Tights are designed as a layer, so you wear them under a skirt, a dress, shorts or a long tunic, whereas leggings make that layer optional. For example, a hip-length sweater over leggings is a complete outfit, while the same sweater over sheer tights still needs a skirt.
US import law draws the same line when it sorts garments into tights or pants. An October 1991 classification ruling concluded that tights are "a form of hosiery" and that leggings are "more in the nature of trousers" (ruling HQ 088454). A May 2022 ruling on a set of leggings said it again: they are "not tights" because "they are not articles of hosiery" (ruling N325680).

Leggings vs tights vs pantyhose vs stockings
Pantyhose and stockings sit on the hosiery side of the line with tights. Pantyhose are sheer tights with a fitted panty section at the top, and in the US the two words are often used for the same thing. The fashion dictionaries quoted in that 1991 import ruling even describe tights as "one-piece pantyhose with or without feet." Stockings are two separate leg pieces that stop at the thigh and stay up with a silicone band or a garter belt. Here is how all four compare, and on a phone you can swipe the table sideways.
| Leggings | Tights | Pantyhose | Stockings | |
|---|---|---|---|---|
| Garment family | Pants | Hosiery | Hosiery | Hosiery |
| Coverage | Waist to ankle or calf | Waist to toes in one piece | Waist to toes, panty section on top | Thigh to toes, two separate legs |
| Feet | None | Usually; footless styles exist | Yes | Yes |
| Opacity | Opaque | Sheer to opaque, graded by denier | Mostly sheer | Mostly sheer |
| Worn alone? | Yes | No, under a skirt, dress, shorts or long top | No | No |
| How it stays up | Waistband | Waistband | Waistband | Silicone band or garter belt |
| Snags and runs | Rare: a dense knit | Common in sheer deniers | Common | Common |
| Specialty styles | Yoga, capri, pocket and flare cuts | Footless, fleece-lined, fishnet, compression | Control-top, sandal-toe | Stay-ups, seamed |
The last row is where most mix-ups start: compression tights and running tights are sold as a sports category of their own. Many of them are opaque and footless, which means they pass all three tests as leggings whatever the label says.
Fishnet tights vs fishnet-print leggings
Fishnet is the clearest case of a look that belongs to tights. Real fishnets are an open net knit, so they fail Test 1 on purpose: the skin shows through every hole. A fishnet-print legging copies that look on a solid fabric. FIERCEPULSE makes leggings only, and our fishnet designs are a high-definition printed effect: a photo-real net over a skin-tone base, on a knit that is never see through. We checked our own catalog to show exactly where the line falls.
What we counted in our own catalog
On 23 October 2026 our team analyzed every active FIERCEPULSE product with "fishnet" or "tights" in its name. We pulled them from our store records and sorted them by product type.
- 39 active products carry a fishnet design, across three prints: Fishnet Tights Print (13), Printed Sparkle Fishnet Effect (15) and Spiderweb Fishnet (11). Five of the 39 are sample-sale pieces; the other 34 are made to order.
- 13 products have "Tights" in the name. Every one of them is a legging, capri, short, sports bra or tank top with a printed fishnet.
- 0 products are hosiery. None of the 40 product types in our store is tights, pantyhose, stockings or socks, and none of the 39 fishnet pieces has a foot.
What this means for you: the word "tights" in a product name describes the look, not the garment. Run the three tests on the product photos and the description, and you will know what you are buying from any brand.
Looks like tights, wears like leggings
Fishnet Tights Print Leggings
A black fishnet with small hearts, as a high-definition printed effect on our mid-rise Leggings cut. There is no open mesh, so there is nothing to ladder or catch on a ring. Sizes XS to XL, $88.99, made to order.
See the fishnet printThe same print also comes in our high-waisted yoga leggings cut and as cropped capris. On a skin-tone base, the effect reads as bare legs under a net from a few steps away. Up close, it is an opaque, squat-proof knit with four-way stretch that moves like any other pair.

Which one should you wear?
Choose leggings when they are the outfit
Pick leggings for anything where your legs are the main layer: workouts, travel days, errands and casual weekends. They take the most wear, they cover fully, and you can style them with a long sweater, an oversized shirt or a short jacket. Every pair of FIERCEPULSE leggings also carries UPF 50+, which matters on an outdoor walk in a way sheer hosiery cannot match.
Choose tights when they are the layer
Pick tights when the skirt, dress or shorts on top is the outfit and you want a finished leg underneath. Sheer deniers suit formal events and the office, while opaque deniers add color and warmth in the colder months. If you are trying to decide between the two for a specific outfit with a dress, our guide on how to wear leggings with a dress the right way covers lengths, shoes and proportions.
Choose a tights-print legging when you want the look without the fragility
A fishnet or sparkle-fishnet print gives you the evening look of hosiery on a garment you can wear by itself. It suits a concert, a night out, a Halloween costume or a bold everyday outfit, and it does not run the first time it meets a car door.
FAQ
Are leggings called tights?
Sometimes, depending on where you are. In the UK and Australia, "running tights" and "gym tights" often mean leggings, while in the US "tights" usually means hosiery. If the garment is opaque, footless and worn without a layer on top, it is a pair of leggings whatever it is called.
What is the difference between tights and pantyhose?
In American usage, pantyhose are sheer tights, usually with a fitted panty section at the top, and the two words often overlap. In British English, "tights" is the everyday word for both. Opaque styles are almost always called tights.
What is the difference between stockings and leggings?
Stockings are hosiery: two separate sheer leg pieces with feet that stop at the thigh and stay up with a band or garter belt. Leggings are one opaque, footless garment from waist to ankle that you can wear as pants.
Can you wear tights as leggings?
Only if they pass the opacity test. Thick, opaque tights can stand in for leggings under a hip-length top, but sheer and semi-opaque deniers show skin and are made to be worn under another layer.
Are fishnet print leggings see-through?
No. On FIERCEPULSE fishnet-print leggings, the net is a high-definition printed effect on an opaque knit, so the fabric is never see through. The skin-tone base only makes the net look like it sits over bare legs.
