Denier - unit used in measuring the fineness of yarns, equal to the mass in grams of 9,000 metres of yarn. Thus 9,000 metres of 15 denier nylon, used in nylon stockings, weighs 15 g/0.5 oz, and in this case the thickness of thread would be 0.00425 mm/0.0017 in. The term is derived from the French silk industry; the denier was an old French silver coin.

Tights for the Business Lady What to Choose:

- Neutral tones that complement with a bottom part of the wardrobe;

- In winter time choose darker colors, thick and opaque;

- In summer time choose sheer textured tights.

What to avoid:

- Bright colors and sticking textures, anything that's not go along with your wardrobe. Your tights should not stand out, but implement your elegant image;

- Cotton or shimmer.

Tights wear much longer, if you properly take care of them. You should hand wash them with soft cleaning liquids and you shouldn't squeeze them hard while washing. Dark colored tights may bleed. Always wash similar colors together. Powders and liquids with defecate effect are not suitable. After giving it a swill, you should wring your tights and lay them down onto soft towel. They shouldn't be dried neither on radiator or any other heater nor in the sun.

Before putting on the tights you should take off rings, bracelets and other jewelry (some women use thin knitted gloves for this purpose). Especially should be careful ladies, who have long nails. You should also keep toenails in perfect condition and regular pedicure is necessary.
