Socks with a tuxedo: black, fine and over-the-calf

Socks are the item few people look at closely and everyone feels. The rule is short: black, thin, in silk or fine cotton, and long enough that no band of skin shows between sock and trouser hem when you sit or cross your legs. Get it right and nobody notices. Get it wrong and you are looked at all night.

Black, thin, silk or fine cotton

An evening sock should have these qualities:

• Pure black, matching the shoe and merging with the trouser. A black sock under a black trouser lengthens the leg line and keeps the figure tidy.
• A thin yarn: silk, mercerised cotton (cotton treated for sheen and smoothness) or very fine merino. A thin yarn lets the shoe sit properly on the foot, especially a slim, patent-leather evening shoe.
• A smooth, slightly glossy surface. Chunky ribs, thick wool or raised patterns are out of step with an evening.
• A close knit with moderate elasticity. Good elasticity keeps the sock in position without wrinkling at the ankle.

In a hot, humid city such as Ho Chi Minh City, silk or fine cotton feels better than wool. A good pair holds its shape for many hours, which makes the price reasonable for an important night.

Long enough that no skin shows when seated

This is the key point. The right sock reaches the calf (over-the-calf), longer than an ordinary ankle sock. The reasons:

1. A tuxedo is often worn seated for hours: at a banquet table, in theatre seats, over dinner. When you sit, the hem rides up.
2. A short sock leaves a strip of bare skin between sock and hem. That image undoes the polish of even a beautifully made suit.
3. An over-the-calf sock keeps its coverage when you cross your legs or step up a stair.

If your socks tend to slip, use garters. Our piece on sock garters explains how. Some over-the-calf socks have a light elastic band that does not squeeze, but test them at home first.

Coloured socks for creative black tie

When the dress code loosens, socks are the easiest place to add personality without upsetting the suit. For creative black tie, or a wedding with its own colour scheme, you could choose:

• A deep shade in the same family as the suit: dark navy socks with a navy tuxedo, burgundy socks with a wine-red tuxedo.
• A fine, small pattern: thin stripes, tiny dots, a small motif on a dark ground.
• A colour borrowed from the bow tie or pocket square: see adding colour to a black tuxedo.

A few limits: coloured socks pair well with black or dark shoes, limited to one or two colours, and the pattern should not be large. On an outfit that already has several features, such as TUX-126, a red jacquard with copper-gold pattern and beaded lapels, the socks should return to black so there is no third colour. With a plain black tuxedo like TUX-067, pure black with a shawl lapel, a muted coloured sock is a good place to echo a shade from the tie.

If the event is strict black tie, stay with black socks. Coloured ones there can look like a deliberate attempt to be different.

The white sock error

The white sock is the most visible mistake with a tuxedo, because:

• It creates a bright band between a black shoe and black trouser, dragging the eye down to the feet.
• White socks suggest sportswear or a uniform, the opposite of the evening mood.
• Ballroom lighting or a camera flash makes white socks stand out even more.

Two other common errors: socks that stop at the ankle, showing skin when you sit, and grey, brown or beige socks that clash with the shoe and trouser. Avoid thick socks, which make shoes feel tight.

A tip from the Mon Amie workroom

At your fitting, bring the socks and shoes you plan to wear. The tailor will set the hem to touch the shoe and cover the sock correctly. Book a fitting at a showroom or see our bespoke tuxedo page.
