Pantyhose are sheer, footed hosiery; tights are thicker footed (or footless) hosiery; leggings are opaque, footless stretch pants worn as outerwear.
For the full breakdown, see our best Pantyhose guide.
A cold morning, a dress already on, and three drawers of black fabric that all look the same under the closet light. The three categories split on two things: how much leg they cover and how thick the knit is. Denier, the yarn weight behind every sheer-versus-opaque decision, sorts them faster than any label on the package.
What Separates Pantyhose, Tights, And Leggings?
Construction and thickness do the separating, not the marketing copy. Pantyhose and tights are each a single garment that joins briefs to leg coverings and runs waist to toe. Leggings are stretch trousers that end at the ankle or lower calf and leave the foot bare.
Pantyhose sit at the sheer end: nylon and elastane knit thin enough to show skin tone, usually 3 to 40 denier. Tights use heavier yarn, commonly starting around 40 denier and climbing into ribbed, patterned, or insulated territory. Leggings are generally fully opaque and built from cotton, polyester, nylon, or spandex blends meant to be seen as pants.
One more distinction that trips people up: stockings are not pantyhose. Stockings are separate pieces per leg that stop at the thigh, with no joined panty section.
How Does Denier Decide Sheer Versus Opaque?
Higher denier means thicker yarn and less transparency, but it is not a guarantee. Denier measures yarn weight, not the finished fabric’s opacity, and the two diverge once color, knitting density, fiber blend, finish, and stretch enter the picture.
A low-denier tight stretched taut over a knee reads sheerer than the same tight relaxed at the ankle. That is why a 40-denier pair in black can look more solid than a 50-denier pair in a pale shade. Check coverage in the lighting you’ll actually wear it in, and move around before deciding.
If a sheer, polished finish under a dress is the goal, thin hosiery does that job and nothing else does it better. A tested shortlist of sheer styles makes that hunt quicker than guessing at denier numbers.
Which One Fits Your Outfit And Season?
Match the garment to the occasion and the weather, then check the feet. Footed hosiery rules out open shoes and bare-ankle looks; footless styles and leggings keep the ankle free.
| What You Need | Best Choice | Why It Works |
|---|---|---|
| Sheer, refined look under a dress | Pantyhose | Waist-to-toe, lightweight, low opacity |
| Warmth and coverage in cold weather | Tights | Heavier yarn, denser knit, more opaque |
| Wearing it as pants | Leggings | Opaque, footless, made for outerwear |
| Open shoes or bare ankles | Leggings or footless tights | No fabric over the foot |
| Exercise or athletic use | Performance leggings | Moisture-wicking, compression, pockets |
| Color, pattern, or texture | Tights | Widest range of weaves and finishes |
| Layering under shorts or skirts | Pantyhose or tights | Designed as layering pieces, not pants |
What Do Shoppers Get Wrong Most Often?
The biggest error is treating “tights” and “pantyhose” as interchangeable everywhere. US retailers apply the labels loosely, and some use “tights” for sheer hosiery too, so the word on the package is a starting point rather than a rule.
Assuming every tight is opaque runs a close second; tights span sheer to solid, and only the stated denier or opacity tells you which you’re holding. Swapping leggings for hosiery is the third miss, since leggings are outerwear and pantyhose is a layering piece. Denier comparisons across brands mislead for the same reason as above: fiber and knit change the result.
Sizing deserves a mention. Use the manufacturer’s chart with height, weight, waist, hip, and inseam rather than a generic category guess. Undersized hosiery rolls, sags, and runs at the seam. Skip anything with damaged fabric or exposed elastic, and treat compression tights as a medical question rather than a fashion one if you have circulation concerns. Sheer fabric snags on rings, rough nails, and zippers, and the care label governs washing heat, bleach, and softener.
