When you go to school or to a regular shop you don't really think about what you're going to wear it can be a plain t-shirt and jeans, it can be a comfortable hoodie and leggins but when you go to a special occasion like a wedding for instance you would think abourt what you wear is it appropriate for the occasion? You can't be wearing black for a wedding, you should wear white. For a funeral you usually wear black. On sundays if you go to the church you can't be wearing a mini skirt and a extra tight top, you need to dress for the occasions. Same for a party, anniversary, ect

Hope this helps Allegra xx
