An answer is yeas and no. If you are kind of a girl who like princess and wearing pink and very subtle clothes you should not change it. Most important think is to feel comfortable in your clothes. Models supposed to be an icon of fashion but it does not mean that you should follow blindly every new fashion. You can not follow celebrities; especially women are wearing tiny clothes on them. They are usually surrounded with their securities and moving only by car. Can you imagine getting on to your car dressed in transparent top with no bra or with trousers and just bra? Can you imagine walking dressed like models or celebrities on the street? Celebrities are showing off like that only at TV, privately they will wear common clothes, unless there would be some set picture session and they would dress and put make especially for photo session.
At the moment paparazzi started taking pictures of stars in unexpected moments. We can see them in normal daily clothes as we are wearing for work or shopping and in dirty clothes.
You should create your own fashion, you can observe others, use their clothing suggestions but only if you will look in these clothes.
Slim woman or man
If you are slim it does not mean that you won’t have problem in finding clothes for you. You can have even more problems as your body has sharp shape.
Normal build woman or man
This is the best structure of the body. It is a build which you should have as it will be easy for you to buy clothes and you will just look nice and healthy. It is not always good to be too slim.
Large man or woman
If you are just very tall and obviously have big feet and other parts of body you can consider custom made clothes, but only if you can order them in a shop in which they are sewing and selling them – the price will be the same then.
If you are overweight you can also order custom made clothes.
