How to Buy Tights Online in the UK: Denier, Sizing and Making Them Last

Why tights are the hardest thing to buy blind

Tights are the one item of clothing you can't try on in a shop either. Most retailers won't let you open the packet, so the changing room was never going to help. That's oddly good news: buying online is no more of a gamble than buying on the high street — as long as you know what you're reading on the label.

What makes it risky is the returns situation. More on that below, because it shapes how you should shop.

Start with denier, then ignore it slightly

What denier actually means

Denier is the weight of the yarn. Higher number, thicker and more opaque; lower number, sheerer and more fragile. As a rough map:

• Very sheer: barely there, best for warm days and evening wear
• Sheer to semi-opaque: the office staple
• Opaque: full coverage, no skin showing through
• Heavyweight: winter warmth, often with a fleecy or wool blend

Denier tells you thickness. It doesn't tell you warmth, how opaque they'll look on your skin tone, or how well they'll spring back after a day at a desk.

The awkward middle

Semi-opaque tights are the trickiest buy. On one pair they read as a soft tint; on another they go patchy over the knee. If you want full coverage, buy opaque and stop hoping. If you want a hint of colour, buy sheer.

Sizing: the packet numbers versus your actual legs

Height and hips matter more than dress size

Most decent tights are sized by height and weight, or height and hip measurement. Dress size is a rough guide at best. If you're between sizes, go up: tights that are too small roll at the waist, pull at the toe and ladder at the stress points.

Petite, tall and extended ranges

Tall ranges add length through the leg. Petite ranges shorten it. If you're tall and buy a standard pair, the crotch sits low and the waistband ends up somewhere unhelpful. Worth paying attention to if you've spent years hitching them up.

When the size chart lies

Read the reviews that mention fit rather than colour. "Runs small" and "baggy at the ankle" are the two phrases worth searching for.

Fabric blends and what they actually do

Nylon gives strength, elastane gives stretch and recovery. A higher elastane content means less bagging at the knee by the end of the day — that's the single biggest difference between a pair that survives and a pair that sags.

Wool and cotton blends are warmer and breathe better. Cotton feels drier against the skin; wool is warmer but itchier and needs gentler washing. "Thermal" on the packet is a marketing word — the blend tells you far more than the adjective.

Ladder-resist and support

Ladder-resist knits genuinely help, but they're not indestructible. A sharp zip will still win. Support tights are firmer and compress the leg: good if you're on your feet all day, harder to get into on a humid morning.

Details worth checking before you pay

Waistbands and gussets

A wide, flat waistband stays where you put it. Thin elastic rolls. A cotton gusset is standard on better pairs and worth confirming before you order.

Toe seams

A visible seam across the toes rules out open shoes. Look for sandal toe or seamless descriptions if you plan to wear them with anything but closed footwear.

Sheen

Matte finishes read smarter under office lighting. High shine can look like stage wear once you're under a strip light. If in doubt, matte.

Buying for a British year

Winter

Layer a sheer pair under an opaque one for warmth without bulk — it works better than one thick pair. Heated offices bring static; a light rub of moisturiser on your legs before you pull them on helps.

Check the inside of your boots for rough zips and seams. That's where most winter pairs die.

Spring and autumn

Semi-opaque in a neutral shade covers the awkward months when it's too cold for bare legs and too mild for wool.

Summer

Sheer, low denier — and honestly, ask yourself whether you want them at all. If it's for a specific event, buy one pair and test it in advance.

Party season

Sparkle, fishnets and patterned pairs are where online shopping wins on choice. Buy early enough to try them on with the outfit, not the night before.

Returns, hygiene and the awkward bit

Hosiery is often treated as non-returnable once the packet is opened, on hygiene grounds. Policies vary, so read the returns page before you order rather than after.

The practical approach: buy one pair, try it on over clean skin, and only then order more. Never order five pairs in different sizes hoping to send four back — you may not be allowed to.

Also check whether the packaging has to stay intact, and keep the outer bag until you've decided.

Care: making a pair last past three wears

• Wash in a mesh laundry bag on a cool, gentle cycle
• Skip the tumble dryer entirely
• Take rings off before you pull them on
• Roll them on rather than bunching them up
• Store flat or rolled, not stretched over a hanger
• Keep a spare pair of the same shade — matching a discontinued colour later is a nightmare

A small ladder can be stopped with a dab of clear nail varnish at the top of the run. It's a temporary fix, not a repair, but it gets you through the day.

A quick checklist before you click buy

• Denier matches the season and the coverage you actually want
• Size chosen by height and hip, not dress size
• Enough elastane to recover its shape
• Waistband and gusset described on the listing
• Toe seam suits your shoes
• Returns policy checked before ordering
• One pair first, more later

Get those right and tights stop being a gamble. Get them wrong and you'll be back on the same page next month, which is exactly how the shops would like it.
