We wear clothes according to the weather. Some examples that explain this are as follows:
(a) We usually wear clothes made of cotton fabrics during the hot days of the summer season. This is because cotton feels cool and it absorbs sweat easily.
(b) Woollen clothes are worn in the cold days of the winter season. This is because wool is the warmest of all fibres.
(c) Clothes made of silk fabrics and synthetic fabrics are comfortable when the weather is neither very hot nor very cold.
