Modern clothes are definitely more practical as against traditional clothes.
Almost all people now wear modern clothes.Nowadays even more and more people wear casual clothes.
Jeans are everywhere except at formal parties.T-shirts are common,
too.
They look comfortable and fashionable.However,there are also a lot of people who take the trouble to dress well in formal clothes like shirts,trousers and suits.I find them smart,too.
But then,it is important to hold on to our topic.In my opinion,each type of dress has its place.Modern clothes are ideal for most situations,while casual clothes are worn more freely.As to traditional clothes,they must be worn for special occasions.
I think our students needn't to wear those clothes that are very shine and cool,we should just wear clothes which we feel comfortable.
