The models selected according to the use you need to do.
There are various lengths, short at the waist, mid-thigh midi or long below the knee to reach even the ankle.

And the yarns? In the summer the yarns will be lighter, so in cotton and linen yarn, while in winter we prefer wool, cashmere, angoretta and so on. I don't recommend choosing acrylic garments in both seasons. Choose one, maybe, but quality.

DO YOU COMBINE IT?

It is generally used as a shawl if worn with a sleeveless dress, in this case it will be short to the waist.
The black chosen is the joker. Very nice even if you have a height that allows it, otherwise it opts quietly for the midi.

The long worn also with a white T-shirt and jeans, maybe with a heel 12 heel gives you that casual but chic touch at the same time. Match us with a nice belt and a shoulder bag and you're done. As an alternative to feet, you can put campers, shoes that I love.

The midi can be used exactly like the long one: very bon ton worn with a white shirt and a cigarette pants or wear it with a romantic ballerina, maybe leopard, which is very trendy, or with a comfortable and very fashionable white sneaker.

Keep in mind that the wool cardigan can be a worthy replacement for the coat in the early autumn. Those in thick wool maybe worked in a braid in natural colors, such as cream or warm beige, are versatile, beautiful and very warm.
Even for an elegant ceremony or event you can find solutions that solve the look with extreme elegance. There are short cardigans, trimmed on the neck, ton sur ton, with polished and very refined stones.
