i like wearing different kinds of clothes, but certainly clothes should suit the occasion. when i plan what i’m going to wear i usually think what kind of meeting i have. at school we weren’t allowed to wear sport or bright clothes, we had to wear clothes of formal style. usually i wore a jacket, a blouse and trousers or a skirt. but i didn’t like being dressed that way, as many other students. really i prefer smart clothes to formal. besides i enjoy wearing sport clothes, because i feel comfortable in it. also on my list of likes there are jeans. one of my favourite colours is white, so i like white sweaters, tops and skirts. i usually wear high heeled shoes even if it’s not always comfortable or thick-soled boots. when i go out i always dress up, because i feel better that way. but when i have an official meeting i try to wear formal clothes.
